The EU adopted its largest-ever round of sanctions listings on 12 October, targeting the suppliers behind Russia’s war industry, the Council of the EU announced. The bloc acted as Russia keeps killing Ukrainian civilians every day, while US President Donald Trump eases sanctions on Russian diesel.

Russia’s planned winter campaign against Ukraine’s infrastructure depends on arms factories fed by a web of component suppliers and on oil revenue that still flows despite Ukraine’s refinery strikes, so every supplier cut off from that web raises the cost of waging it. As Washington eases off, Europe’s own pressure has a gap: its ports still take record volumes of Russian Arctic gas, and a full ban on long-term contracts starts only in 2027.

Missile suppliers top the list

More than half of the new listings hit the supply chain for ballistic missiles that Russia “uses to kill Ukrainian civilians every day,” EU foreign policy chief Kaja Kallas said in the statement. Russian attacks killed more than 150 people in the past week, Ukrainian President Volodymyr Zelenskyy said on 11 October.

The list names 826 Russian companies, mid-level firms the Council calls the “core” of Russia’s arms industry, with at least €20 billion in yearly turnover, and 743 people who run them. They make parts for missiles, drones, and military aircraft, from semiconductors and radars to explosives and navigation systems. Their assets are frozen, EU firms may not finance them, and the executives may not enter the EU.

Foreign ministers ratified a deal EU envoys reached on 7 October. Ukraine’s sanctions commissioner Vladyslav Vlasiuk said 60% of the listings came from Ukrainian proposals.

Ministers reject the diesel deal

EU foreign ministers in Luxembourg vowed to keep the sanctions despite Trump’s diesel deal with Russian President Vladimir Putin, Euronews reported. Kallas addressed Washington directly as she arrived.

“The US is our biggest ally, but our message is clear: if we want to end this war, the only way we can do this is (by) putting more pressure on Russia,” Kallas said.

Irish Foreign Minister Helen McEntee called the deal “concerning,” and Lithuanian Foreign Minister Kęstutis Budrys said it was “not the European way.” Kallas warned that an energy truce covering only refineries would favor Russia, since Ukraine has one refinery and Russia “plenty.”

Trump announced the diesel deal on 9 October, and the US Treasury waived sanctions on Russian diesel until April 2027. Zelenskyy said the EU would provide about €3 billion more in military aid this week.

Washington presses Kyiv

Trump expects Ukraine to stop hitting Russian refineries under his proposed energy ceasefire, a White House official told Axios. Zelenskyy said Kyiv would halt such strikes if Moscow did the same. On 10 October, Trump told reporters it was time for Ukraine to get a new president. Germany’s foreign minister, Britain’s defense secretary, and a senior lawmaker from Chancellor Friedrich Merz’s party backed Zelenskyy, while the Kremlin sided with Trump.

Zelenskyy offered to hold elections after a 60-day ceasefire, and Kallas said elections are impossible while the war goes on. The Institute for the Study of War assessed that Russia exploits Ukraine’s legal ban on wartime elections to drag out the war.

Russia and four allies began five-day military drills in Belarus on 12 October, the Russia-led Collective Security Treaty Organization (CSTO) said. The troops are rehearsing peacekeeping and a biological-threat response. Minsk insists the drills target no one, while Belarus’s army chief calls them deterrence against hostile states.

Russian troops crossed Belarus to advance on Kyiv in 2022, and it now hosts Russian units with Oreshnik missiles and equipment guiding attack drones into Ukraine. Every foreign deployment there worries Kyiv and neighboring NATO members, which blame Minsk and Moscow for border pressure.

Riot police and drone crews in a “peacekeeping” drill

Belarus, Kazakhstan, Kyrgyzstan, Russia, and Tajikistan brought more than 1,500 troops and over 300 weapons and vehicles, including about 80 drones, The Moscow Times reported, citing the bloc. Armenia, the sixth member, is not among them. The peacekeeping drill runs in Vitsebsk Oblast, bordering Latvia and Lithuania, with Belarusian riot police and internal troops joining, the bloc’s command said.

Up to 60 railcars: Belarus wires a border base to take in military trains

Russia sent motorized rifle, reconnaissance, electronic warfare, and drone units from its Central Military District, the CSTO said. Russia, this year’s chair, prioritized peacekeeping readiness and the joint biological protection and medical unit, a bloc general said.

Belarus’s military insisted the drills are planned, yet its army chief called them “one of the measures of strategic deterrence against aggressively minded states” and claimed the West is “effectively preparing for a new hot war.”

Pressure on Belarus’s neighbors

In Latvia, armed, masked escorts from Belarus tried to force migrants across this month, the military said, and raiders stole border cameras hours later. Estonia’s police and border guard chief warned migration pressure could jump before winter, as Russia eases entry from countries like Ethiopia and Belarus passes migrants on to the EU. Lithuania posted up to 100 soldiers on its border with Russia’s Kaliningrad, and in September NATO’s Italian jets downed a drone that crossed in from Belarus. On 9 October, Minsk summoned Ukraine’s envoy over an alleged drone strike on a Belarusian truck in Russia, and Kyiv rejected the “absurd accusations” of “an accomplice in the crime of aggression against Ukraine.”

Belarus keeps its army on alert

In September, Belarusian armor drilled near the Suwałki Gap, NATO’s land link to the Baltic states, and Lukashenka said the whole army would be checked, up to mobilization. On 12 October, he ordered a snap check of a 6th Separate Guards Mechanized Brigade battalion, state news agency BelTA reported. European spy agencies also warn of more Russian assassination plots against defense executives.

Ukraine’s intelligence still rates the threat from Belarus as low, but each new contingent, missile unit, and airborne brigade there widens what Kyiv and NATO’s eastern flank must watch.

Estonia’s answer to the US-Russia diesel agreement: deals with dictators lead to hell. Prime Minister Kristen Michal wants the European Council to discuss giving Ukraine more aid so it can destroy Russia’s oil refineries, after sharply criticizing the US decision to strike a diesel deal with Russia, ERR reports.

Washington has eased sanctions on Russian diesel, a move Ukraine says funds a war that has killed more than 80 Ukrainian civilians in two days. Estonia’s answer is to go the opposite way and help Ukraine hit the source of that fuel, the refineries, harder.

"It is worth discussing in Estonia and at the European Council next week whether we can quickly contribute more to Ukraine so they can blast Russia's oil refineries to smithereens," Michal says.

He casts the US deal as a historic error. Innocent people are being killed for gas and fuel money, Michal warns, saying that the promised fuel may never arrive. For years, the US urged allies to drop Russian fuel, and Estonia did, so cutting Moscow’s revenue must continue, not reverse, he adds.

Mihkelson: Russia's strategic goals remain unchanged

Meanwhile, Marko Mihkelson, chair of the Riigikogu Foreign Affairs Committee, says that Russia's strategic objectives remain the same as they were before: to rebuild its empire, beginning with the subjugation of Ukraine, and to dismantle the Euro-Atlantic system of collective defense.

"That is why European allies still have only one way to prevent this war of aggression from spreading: to do everything possible to ensure that Russia’s strategic objectives fail and that the imperial wars launched by the Kremlin end in defeat," he says.

This clear strategic objective should also serve US interests, he continues, adding that "Russia’s long-standing ambition, pursued in concert with China and Iran, to undermine America’s global leadership is entering a decisive phase."

Ukraine is offering Estonia something no ally can buy off the shelf: how to fortify against Russia, learned under fire. Ukraine’s Defense Ministry announced, following a meeting between Defense Minister Yevhenii Khmara and his Estonian counterpart, Martin Herem, that Kyiv and Tallinn plan to develop joint defense projects, share data, and establish joint ventures.

Both sides agreed to strengthen their defense cooperation in a declaration signed in June, according to the President’s Office. The partnership is gaining momentum as German intelligence warns that Russia may be preparing military action against the Baltic states, Welt reported.

At the talks, the two sides went over the battlefield situation, Ukraine’s priority needs, and practical steps to deepen the partnership, the ministry said.

Ukraine’s war experience, packed for export

Ukraine’s experience of modern war was a central theme of the meeting, and it can already help Estonia strengthen its own defense against new threats, the ministry reports. During the visit, the Ukrainian delegation walked the Estonian representatives through its work on modern fortifications, including underground shelters.

“Ukraine is scaling up fortification solutions based on real war experience. We already know how to build defenses and adapt them to new threats. I am sure this expertise will be useful to Estonia,” Khmara said.

A debt of thanks to a steady backer

Khmara thanked Estonia for its consistent help, singling out its decision to give 0.25% of GDP each year to support Ukraine. He also noted Estonia’s leading role in the IT coalition, a group of states that helps build Ukraine’s military communications and cyber capabilities, as well as its active work with other partners.

The meeting was one of Herem’s first with Kyiv as defense minister. A former commander of Estonia’s armed forces, he took the post on 16 September after Hanno Pevkur resigned over a 70-million-euro procurement scandal involving artillery shells meant for Ukraine, Euronews reported.

The minister confirmed Ukraine is ready to deepen practical defense cooperation with Estonia and to work on joint solutions that strengthen the security of both countries.

The EU Delegation and all EU embassies will keep working in Kyiv despite Russia's warning that foreign diplomats should leave or risk their lives, EU Ambassador to Ukraine Katarína Mathernová said on 4 October. Poland and Estonia also said their embassies would stay, calling the threats an attempt to intimidate Europe.

Russia attacks Kyiv daily as Moscow tries to make the city unlivable. Alongside the strikes, it now threatens the foreign missions that anchor Ukraine's support in the capital.

"We are staying"

Russia's Foreign Ministry singled out the embassies still working in Kyiv and the foreign officials who keep visiting Ukraine, Mathernová wrote. Moscow claimed that if something happened to them, the responsibility would be theirs.

"The responsibility for russian attacks belongs to russia! Not to anybody else," Mathernová wrote, adding: "Moscow wants to scare Europe into reducing its support for Ukraine. That will not happen."

The EU Delegation continues its work while taking the security of its team seriously, she added.

She pointed to the morning's strike on the Northern Bridge, saying the repeated attacks disrupt the connections between the two banks of the Dnipro. People worry about getting to work, reaching their families, and getting home safely, she wrote.

Poland and Estonia keep their embassies open

Poland's Foreign Ministry said it had no intention of changing how its Kyiv embassy works. The Kremlin's threats and calls for diplomats to leave show it is trying to intimidate Europe and undermine support for Ukraine, the ministry said. Such threats contradict international law and will not work, it added.

Estonia's Foreign Ministry said its embassy stays in Kyiv and its support for Ukraine remains firm. Russia's threats only strengthen Estonia's resolve to stand with Ukraine, the ministry said.

“Mr Putin, put an end to this senseless war”: Merz in Kyiv, with €1 billion in military aid

The European Commission also responded. Russia's threats show the Kremlin is losing the war and losing its self-control, Commission spokesperson Christian Wigand said, Suspilne reported.

More aid, more sanctions

This year alone, the EU has approved €28.3 billion ($32.3 billion) in defense procurement plans for Ukraine and is releasing another €6.6 billion ($7.5 billion) linked to military aid, Mathernová wrote. It is also moving forward with its biggest-ever sanctions listings against Russia, and this week imposed new sanctions over the deportation of Ukrainian children.

German Chancellor Friedrich Merz came to Kyiv on the same day, as Russian attacks on the city continued. He and Zelenskyy visited the National Academy of Sciences building, hit by a Russian drone in September, and Zelenskyy thanked him for coming despite the air raid alert, calling it "a needed and brave signal," in a post on Telegram. Germany remains a reliable partner at Ukraine's side even in difficult times, Merz wrote.

Estonia says Russia ordered the August arson attack on Milrem Robotics’ Tallinn premises, an Estonian defense company supplying Ukraine with military ground robots.

Russian sabotage operations have been expanding across Europe in recent months, targeting companies, infrastructure and supply chains connected to Ukraine’s defense effort. European authorities have linked or investigated suspected Russian involvement in arson and other sabotage attempts in several countries, as Moscow seeks to disrupt support for Ukraine and intimidate its European backers.

Foreign Minister Margus Tsahkna said on 29 September that information gathered by Estonia’s Internal Security Service showed the fire at Milrem’s Tallinn premises on the night of 14–15 August was a Russian intelligence-directed sabotage operation. Estonia summoned Russia’s chargé d’affaires over the attack.

Three suspects detained

Estonian authorities had already detained three suspects in connection with the arson, with the suspects apprehended in Latvia. Tsahkna said the perpetrators had been taken into custody and no longer posed a threat to Estonia.

When the investigation was first announced in August, Estonian authorities had not publicly established a Russian connection or disclosed evidence linking Moscow to the fire.

Milrem supplies robots to Ukraine

Milrem Robotics makes THeMIS unmanned ground vehicles, which have been used by Ukrainian forces since 2022 for tasks including transporting ammunition, food and other supplies, evacuating wounded troops, and mine clearance.

The company said in August that the fire had not disrupted its production or deliveries to Ukraine. More than 200 of its robotic systems are expected to be operating in Ukraine by the end of 2026, including more than 150 vehicles funded by the Netherlands.

The attack is part of a growing series of suspected sabotage operations targeting companies and facilities connected to Ukraine’s defense effort. In August, Slovak authorities foiled an attempted arson attack on a Ukrainian drone factory, while European investigations have also examined suspected Russian involvement in attacks on defense-related facilities in Czechia, Lithuania and Bulgaria.

Estonia says sabotage will not weaken Ukraine support

Tsahkna said Russia’s campaign is intended to intimidate European countries, divide allies and weaken their support for Ukraine.

“Russia’s sabotage campaign will not achieve its objectives,” the Estonian Foreign Ministry said, adding that Estonia and its allies would continue increasing pressure on Russia and supporting Ukraine.

Tsahkna said Estonia would respond to the attack by increasing both its support for Ukraine and pressure on Russia.

Lithuania is getting its US troops back although the overall American presence in Europe will shrink, Lithuanian President Gitanas Nausėda said. He tied the wider drawdown to Washington's demand that Europe take more responsibility for its own defense. Lithuania's case, he suggested, is the exception.

While waging all-out war on Ukraine, Russia keeps probing Europe with drones and sabotage that stop just short of open attack. Its small Baltic neighbors are already preparing their people for a possible invasion, and American soldiers on their soil have long been the clearest sign that attacking them means fighting the US. With Washington weighing a pullback and telling Europe to fend for itself, each US unit that stays on Russia's doorstep carries more weight than its size.

"There will be fewer US troops in Europe"

Nausėda spoke in an interview with LNK television on 28 September.

"There will be fewer US troops in Europe. This is partly related to what US President Donald Trump says, to the signals the US administration is sending us that Europe must take on more responsibility itself," he said.

Europe must do more for itself, and it is already doing so, Nausėda added. The US presence in Lithuania matters not only for its military power but also for deterrence, he argued.

"The presence of these troops is precisely what reduces the likelihood of military conflict or military aggression," he told LNK, ELTA reported.

"The heavy battalion will be here"

Nausėda called the decision a kind of encouragement for Lithuania. "As the overall number of US troops in Europe decreases, in Lithuania that number will at least remain, will not decrease, and perhaps will even be slightly larger," he said. "In any case, the heavy battalion will be here."

The battalion will keep its Abrams tanks, but an engineer battalion will replace the artillery battalion, Nausėda said on LRT's Savaitė program. The rotation will again last nine months. The Americans will number roughly as before, over 1,000, Defense Minister Robertas Kaunas said.

Estonia has also secured the return of US troops, at least temporarily, LRT noted.

Trump announces 5,000 US troops to Poland — one week after US froze scheduled combat-team rotation and amid Russia’s threat

More than 1,000 US troops began leaving Lithuania when their rotation ended in early June, and no replacement arrived, LRT said. It was the country's first gap in the US presence since 2020. American heavy battalions have rotated through Lithuania since 2019.

The Pentagon is weighing a withdrawal of about 25,000 US troops from Europe, and possibly as many as 40,000, NBC News reported, adding that no final decision had been made. About 80,000 US troops are now stationed on the continent. Germany, Italy, and Spain would likely be among the countries most affected.
