President Volodymyr Zelensky on June 15 condemned Russia's latest mass attack against Ukraine, calling the strikes on energy infrastructure "a spit in the face of everything the international community is trying to do to stop this war."

Earlier in the day, Russia targeted the city of Kremenchuk in Poltava Oblast with a combined missile and drone attack, damaging energy and agricultural facilities. The strike involved nearly 200 drones and missiles, including both cruise and ballistic missiles. The attack came shortly after a phone call between U.S. President Donald Trump and Russian President Vladimir Putin.

In his nightly address, Zelensky said the attack on Kremenchuk was "deliberately and treacherously planned to target our civilian infrastructure" and that Russia intended to damage energy facilities.

"This is Russia's spit in the face of everything the international community is trying to do to stop this war," Zelensky said in his nightly address.

"It happened right after Putin's conversation with Trump. After the Americans asked us not to strike Russian energy facilities. At the same time as Putin tries to portray himself as a mediator for the Middle East ... The level of cynicism is staggering."

Following his call with Putin, Trump claimed he would be "open" to the Russian president acting as a mediator in the rapidly escalating conflict between Israel and Iran. Zelensky rejected the idea of Putin — who has waged war against Ukraine for over 10 years and has taken no steps towards a lasting ceasefire — playing the role of peacemaker.

Putin "is war itself," Zelensky said, urging the international community not to fall for "Russian manipulation and lies."

Zelensky also warned that Russia may be planning additional attacks on Ukraine's energy sector, including nuclear power infrastructure. According to the president, Ukrainian intelligence agencies have obtained evidence of Russia's threat and shared the information with the International Atomic Energy Agency (IAEA) and the Trump administration.

"Russia is planning further attacks on our energy sector — attacks that may be less visible to the world right now because all eyes are on the situation in the Middle East," he said.

Throughout the full-scale war, Russia has attempted to disrupt Ukraine's power grid through targeted attacks on energy infrastructure. After rejecting a U.S. proposal for a 30-day unconditional ceasefire in March, Moscow instead agreed to a month-long ceasefire on energy attacks.

Russia subsequently violated the partial ceasefire, which ended in in April. The Kremlin continues to refuse calls for an unconditional truce.

With no new US aid packages on the horizon, can Ukraine continue to fight Russia?

The U.S. has not announced any military aid packages for Ukraine in almost five months, pushing Kyiv to seek new alternatives. But time is running out quickly as Russian troops slowly advance on the eastern front line and gear up for a new summer offensive. “While Ukraine’s dependence on

In the early hours of 6 June, Russia conducted one of the largest air attacks since the start of its full-scale invasion, targeting Kyiv, Ternopil, Lutsk, Lviv, and several other cities using a combination of missiles and drones. The Russian assault resulted in civilian casualties — with four people known to have been killed and 25 injured — along with widespread damage to infrastructure and multiple fires.

At the time of reporting, the attack was still ongoing, with several Russian drones remaining airborne over multiple regions.

The mayor of Kyiv, Vitaliy Klitschko, confirmed that as of 6:00, one person was killed and 20 others were injured, 16 of whom were hospitalized. Strikes hit multiple districts, including Solomianskyi, where a school and residential buildings were damaged.

Drone debris caused fires in Darnytskyi, where vehicles were destroyed, and in Holosiivskyi, where building structures were reportedly damaged. Fires also broke out in Shevchenkivskyi and Sviatoshynskyi. Debris fell in Desnianskyi and other parts of the city. Metro lines between “Darnytsia” and “Livoberezhna” were damaged. Some areas on the city’s left bank experienced temporary power outages.

“They were working under fire to help people. Another nine emergency workers were wounded. Some are in serious condition — doctors are fighting for their lives,” Klymenko wrote on Telegram.

A residential building suffered partial destruction and windows were shattered in multiple buildings. Commercial facilities and private vehicles were also damaged. The Oblast Military Administration added that people were evacuated and received medical help, noting that air defenses “destroyed a lot of [aerial] targets.”

Russia launches 407 drones and 44 missiles against Ukraine in overnight assault, Air Force says

Ukraine launched overnight drone strikes on Russian military infrastructure and Russian-occupied power facilities, including an airfield in Rostov Oblast and energy infrastructure in occupied parts of southern Ukraine, leading to damage and power outages.

Millerovo air base targeted in drone attack

In the early hours of 5 June, explosions were reported across Russia’s Rostov Oblast, adjacent to eastern Ukraine’s occupied Luhansk and Donetsk oblasts. According to Russian news Telegram channel Astra, local residents claimed that a military airfield in Millerovo came under drone attack. Acting governor of Rostov Oblast Yuriy Slyusar later confirmed that drones were active in the Millerovo district, though he did not explicitly confirm an attack on the airfield.

He stated that debris from the downed drones allegedly caused damage in the village of Sulin, hit structures on two properties on Dachna Street. One house ostensibly had a partially destroyed roof, while another suffered broken windows and torn electric wiring. He added that “No civilians were injured according to emergency services on the ground. The military continues to repel the enemy’s attack. Information is being clarified.”

Occupied parts of Kherson and Zaporizhzhia oblasts suffer blackouts

In a separate development, Russian-installed “Kherson Oblast governor” Vladimir Saldo claimed that more than 120,000 people in Russian-occupied parts of Kherson Oblast were left without electricity and water after a strike on a main transformer substation.

The hit allegedly occurred at 23:10 and resulted in a total blackout for 192 settlements across seven “municipal districts” – a term not used in Ukraine’s territorial structure – including Henichesk, Novotroitske, and Velyka Lepetykha.

Occupied parts of Zaporizhzhia Oblast reportedly also experienced blackouts. Head of the Russian occupation administration in the region, Yevgeny Balitsky, blamed Ukrainian forces for shelling the area, stating that “no fewer than five explosions were recorded over Melitopol,” along with an attempted strike on a power substation. Power outages were reported in parts of Melitopol, Prymorsk, Enerhodar, and Akimivka.
