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.

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.

Lithuania plans to deploy up to 100 soldiers to support border guards along its frontier with Russia's Kaliningrad Oblast, Defense Minister Robertas Kaunas said on 7 October.

Lithuanian Interior Minister Martynas Katelynas has described the deployment as a preventive measure linked to possible Russian mobilization and a recent incident on the Latvia-Belarus border, where masked, armed escorts tried to push a group of migrants into Latvia. Katelynas said Lithuania could face people trying to avoid mobilization and seeking asylum.

Kaunas said he had granted permission to use Lithuanian soldiers to strengthen border protection for the next several weeks.

 “The order starts being implemented immediately,” he wrote on Facebook.

Russia denies a new mobilization

The Kremlin denies a new mobilization is coming. In early September, Russian President Vladimir Putin called reports of one "complete nonsense" and "an information attack on Russia." Ukraine's military and foreign intelligence services say Russia's General Staff has prepared a scenario to mobilize 600,000 people over 2026 and 2027. On 28 September, President Volodymyr Zelenskyy said that "in effect, the Russians have already begun additional mobilization."

Frontier-station patrols for a couple of weeks, possibly longer

On 8 October, the Lithuanian army said soldiers were being brought in to help the State Border Guard Service from that day. A company-sized unit was planned for the assignment, initially for two weeks, with the option to extend. Soldiers will patrol with border guards in frontier-station areas, while mobile patrols, mobile observation posts, and military police crews may be added as needed. The army described the deployment as preventive and a normal form of interagency cooperation.

Kaunas had told LRT TV the soldiers would stay until 16 October. On the morning of 8 October, he said the deployment "was supposed to start" overnight and that he would check with the army. On 8 October, the Lithuanian army said soldiers were being brought in to help the State Border Guard Service from that day. Kaunas also said that “on the Kaliningrad side” there were no physical barriers, unlike the border with Belarus.

Lithuania says its border guards are stretched

On 8 October, Katelynas said the border guard service’s capacity was insufficient, with shifts growing while officer numbers were not increasing. He said the threat level had not changed. In a Facebook post the previous day, he said the situation at Lithuania’s border was calm and there was no reason to panic. He said Russia was planning mobilization after the elections and that Lithuania may face people trying to avoid it and seeking asylum.

Lithuania's State Border Guard Service had turned back 1,693 people trying to cross illegally from Belarus this year and about 26,300 since the migration crisis began, as reported by ELTA on 8 October. Katelynas said 43 migrants tried to enter southern Lithuania last week and were turned back.

Armed escorts in masks pushed a group of migrants from Belarus toward Latvia and threatened Latvian soldiers, and hours later masked people crossed into Latvia and stole border surveillance cameras, Latvian Interior Minister Jānis Dombrava said on 6 October. Latvia's military described the incident as part of a continuing hybrid campaign on the border, and Ukraine's foreign minister blamed Moscow.

Russia keeps probing the EU's eastern defenses with migrants pushed from its own soil and through its ally Belarus, alongside drone incursions and sabotage that ISW has linked into one Russian pattern across Europe.

Armed escorts threatened Latvian soldiers

Latvian soldiers stopped at least 20 migrants trying to cross the border illegally from Belarus, the Latvian National Armed Forces said. Masked escorts led the group, and this time they were armed, threatened the soldiers, and urged and drove the migrants toward Latvia, the military said.

"Unlike many previous incidents, this time the provocation was particularly demonstrative and aggressive," Dombrava said.

The incident confirms that deliberate provocations and hybrid threats on the border will continue, the armed forces said. Illegal migration is being used as a tool to pressure Latvia's border and, with it, the external border of the EU and NATO, they added.

Belarus began funneling migrants toward the EU in 2021, a campaign Poland's government called a hybrid attack in which the migrants end up as weapons. In 2023, Finland closed its border crossings with Russia, accusing Moscow of the same tactic, and by mid-July Latvia had logged 111 straight days of migrants pushed across from Belarus.

Masked people stole the cameras

Several hours after the standoff, people in masks entered Latvian territory, damaged a distribution cabinet, and stole surveillance cameras, Dombrava said. They returned to Belarus before the border guard patrol could arrive.

"Belarus should understand that such incidents could lead to more serious consequences for Belarus itself," he said.

Ukrainian Foreign Minister Andrii Sybiha said Ukraine stands in full solidarity with Latvia. "Make no mistake: Moscow is behind it," he wrote, adding that Russian President Vladimir Putin "deliberately weaponizes migration, with the help of Lukashenka, to destabilise Europe."

Tunnels, tear gas, and damaged cameras on the border

Latvia's border guards stopped 11,384 attempts to cross illegally from Belarus between the start of 2026 and 24 September. In January, Latvia's armed forces and border guard published evidence that Belarusian security agencies were organizing illegal migration across the border. Latvia has also recorded deliberate damage to cables, distribution cabinets, and camera poles on its eastern border, aimed at slowing the rollout of an automated border control system.

On 22 July, Latvian soldiers fired warning shots and used tear gas against migrants trying to cross. The next day, Prime Minister Andris Kulbergs said Russia and Belarus were stepping up their hybrid war against the Baltic States to distract from Russia's failures in Ukraine. Latvia temporarily halted crossings on the Belarus border on 31 July. In August, Latvian guards found the first tunnel dug from Belarus and turned back 15 migrants who used it.

Latvia's parliament adopted a bill on June 19 that prohibits citizens of Russia and Belarus from purchasing real estate in the country, Latvian media reported.

The bill — which carves out exceptions for EU and Latvian permanent residence holders, Belarusian refugees, and repatriates — establishes the new restrictions under the pretenses of protecting the country's national security.

In addition to citizens, the bill prohibits entities that are at least 25% owned by Russian or Belarusian nationals from purchasing property.

"This is a step to limit the influence and presence in Latvia of persons and companies that are adverse to the country,” said Agnese Krasta, an Estonian member of parliament and one of the authors of the initiative.

Latvia, which borders both Russia and Estonia, is widely viewed as one of the most likely targets for a future Russian attack on NATO or the European Union. As the war in Ukraine continues to rage on, Latvia has taken action to increase civil preparedness measures and has drafted plans to relocate a quarter of its population in the case of war.

EU intelligence and security agencies have warned of mounting Russian sabotage operations, including several arson attacks believed to have been coordinated by Moscow.

Latvia joins Finland in imposing a ban on Russians from buying, as Baltic and Nordic countries continue to impose restrictions on Russia over its aggression in the region.

In September 2022, Latvia imposed entry restrictions on Russian citizens as part of a joint agreement with Lithuania, Estonia, and Poland.

Since the start of Russia's full-scale invasion in 2022, Latvia has been one of Ukraine's most vocal backers.

The Baltic state ranks among Europe's top defense spenders, allocating over 3% of GDP to defense in 2025, according to NATO estimates.
