At least 32 people have been killed in a Russian missile strike on the Ukrainian city of Sumy on Sunday, officials said.

Two ballistic missiles struck the heart of the city around 10:15 a.m. local time as people gathered to celebrate Palm Sunday, according to officials.

Images posted from the scene on official channels showed lines of black body bags lying on the side of the road, while more bodies were seen wrapped in foil blankets among the debris. Video footage also showed fire crews as they fought to extinguish the shells of burnt-out cars among the rubble from damaged buildings.

"On this bright Palm Sunday, our community has suffered a terrible tragedy," acting mayor Artem Kobzar said in a statement on social media. "Unfortunately, we already know of more than 20 deaths."

At least 32 people were killed as a result of the attack, including two children, the State Emergency Service of Ukraine said in a statement. A further 84 people were injured, including 10 children, it said.

Ukrainian President Volodymyr Zelenskyy confirmed that rescue efforts were ongoing and said "dozens" had been killed in the double missile attack.

"According to preliminary information, dozens of civilians were killed and wounded. Only filthy scum can act like this — taking the lives of ordinary people," he said.

The attack on Sumy is the second large-scale attack to claim civilian lives in just over a week, following a deadly missile strike on Zelenskyy's hometown of Kryvyi Rih on April 4 that killed some 20 people, including nine children.

Zelenskyy also called for a global response to the attack. "Talks have never stopped ballistic missiles and aerial bombs. What's needed is an attitude toward Russia that a terrorist deserves," he said.

The strike highlights the urgent need to impose a ceasefire on Russia, wrote French President Emmanuel Macron on X on Sunday.

"Everyone knows it is Russia alone that wants this war. Today it is clear that Russia alone wants to continue with it, showing its scorn for human life, international law and diplomatic efforts made by President Trump," Macron said.

Elsewhere in Ukraine, the mayor of the Ukrainian city of Kharkiv, Ihor Terekhov, said Sunday that a Russian strike had hit one of the city's kindergartens, shattering windows and damaging the building's facade. No casualties were reported.

The strike comes less than a day after Russia and Ukraine's top diplomats accused each other of violating a tentative U.S.-brokered deal to pause strikes on energy infrastructure, underscoring the challenges of negotiating an end to the three-year-old war.

The two countries' foreign ministers spoke at separate events at the annual Antalya Diplomacy Forum, a day after U.S. envoy Steve Witkoff met with Russian President Vladimir Putin to discuss peace prospects.

Trump blames Ukraine for not ending war with Russia sooner

U.S. President Donald Trump blamed Ukraine for not ending the war with Russia sooner by making a deal years ago. The comments were a response to Ukraine’s concerns about being excluded from talks with Russia in Saudi Arabia.

"The Ukrainians have been attacking us from the very beginning, every passing day, maybe with two or three exceptions," Russian Foreign Minister Sergey Lavrov said, adding that Moscow would provide the U.S., Turkey and international bodies with a list of Kyiv's attacks during the past three weeks.

His Ukrainian counterpart, Andrii Sybiha, fiercely contested that claim, saying Saturday that Russia had launched "almost 70 missiles, over 2,200 [exploding] drones, and over 6,000 guided aerial bombs at Ukraine, mostly at civilians," since agreeing to the limited pause on strikes.
