Officials from around the world condemned Russia and its president, Vladimir Putin, as the Ukrainian city of Sumy continued to sift through the wreckage caused by Russian a missile strike that left at least 34 people dead.
Ukraine's state emergency service said two children were among those killed in the April 13 attack when Ukrainians were marking Palm Sunday, while at least 117 others -- including 15 children -- were injured.
The attack prompted European officials to accuse Russia of committing a war crime, while US officials from President Donald Trump to several Republican and Democratic Party lawmakers expressed horror at the death and destruction caused in the second major attack to kill civilians in 10 days.
In an interview that aired late on April 13 on the US news program 60 Minutes, Zelenskyy, who was speaking before the latest attack had occurred, urged President Donald Trump to visit Ukraine to see first hand what Russia was doing to his country even as the two sides talk with Washington about a cease-fire.
"But please, before any kind of decisions, any kind of forms of negotiations, come to see people, civilians, warriors, hospitals, churches, children destroyed or dead," Zelenskyy said.
"You will understand what Putin did."
The Kremlin has denied that either of the attacks targeted civilian infrastructure as it has with multiple allegations of deliberately striking such targets in Ukraine throughout the war, even though repeated attacks on hospitals, schools, energy facilities, and residential buildings have been documented throughout the conflict.
Trump, who has made ending the war a top foreign policy priority since taking office less than three months ago, called the Russian strike on Sumy a "horrible thing."
"I think it was terrible. And I was told they made a mistake. But I think it's a horrible thing. I think the whole war is a horrible thing," he told reporters aboard Air Force One on April 13 as he traveled to Washington from Florida, although he didn't specify what he meant by "made a mistake."
Russia Targeted Crowded Center of Sumy
An RFE/RL correspondent who arrived in Sumy not long after the attack said it occurred "in a very crowded place -- the center of the city" at a time when many Ukrainians would have been going to church for Palm Sunday.
"People walk there with their children," Alyona Yatsyna added. "There are some cafes. All the cars on the street, including public transport -- a whole bus burned to the ground. There's a lot of destruction. A lot of people were killed."
The head of Ukrainian military intelligence, Kyrylo Budanov, said on Telegram that two Iskander-M / KN-23 ballistic missiles had been launched at Sumy from Russia's Voronezh and Kursk regions.
As crews began to clean up debris the day after the attack, locals laid flowers to remember the victims. "It's a huge tragedy," said Serhiy Pask, the mayor of Mykolayivka, a village just north of Sumy. "Unfortunately, it's happening every day."
Global Leaders Condemn Putin Over Sumy Strike
"This is the height of [Putin's] perfidy," Germany's incoming chancellor, Friedrich Merz, told public broadcaster ARD on April 14.
"It was a deliberate and calculated war crime."
Merz, the 69-year-old leader of the center-right Christian Democrats (CDU), reiterated his consistent support for supplying long-range Taurus missiles to Ukraine, stressing that such a move should be made in close coordination with European allies.
"European partners are already supplying cruise missiles," he said. "The British are doing it, the French are doing it, and the Americans are doing it anyway. It has to be coordinated, and if it is coordinated, then Germany should be part of it," he added.
He also pointed to Crimea as a potential target for Ukraine's long-range strikes. "One example would be to destroy the most important land link between Russia and Crimea," Merz added, noting its strategic importance for Russian military logistics.
When questioned about the Sumy attack, Kremlin spokesman Dmitry Peskov on April 14 said Russia's military targets only "military and military-linked targets."
At the news briefing, Peskov also condemned Merz's proposal on supplies of Taurus long-range missiles, warning that such a move "will only lead to a further escalation" of the conflict.
The European Union's top diplomat, Kaja Kallas, said on April 14 in Luxembourg that "all those who want the killing to stop should put the maximum pressure" possible on Russia to agree to a peace plan.
"We have to put the pressure, the maximum pressure, on Russia to really end this war, because it takes two to want peace," Kallas said as she arrived at a meeting of European Union foreign ministers.
UN chief Antonio Guterres, meanwhile, was "deeply alarmed and shocked" by the attack in Sumy, his spokesman stated, saying it "continues a devastating pattern of similar assaults on Ukrainian cities and towns in recent weeks."
US Secretary of State Marco Rubio called it a "horrifying Russian missile attack," while Trump's special envoy for Ukraine, Keith Kellogg, said the "Palm Sunday attack by Russian forces on civilian targets in Sumy crosses any line of decency."
Trump has signaled impatience with the pace of talks to cement a cease-fire in Ukraine with his administration continuing to engage in direct talks with Russian officials, as part of a wider deal aimed at rebuilding bilateral relations.
White House envoy Steve Witkoff flew to St. Petersburg, Russia, to meet with Putin for more than four hours of talks on April 12. Neither Witkoff nor the White House issued any public comment after the meeting, though the Kremlin said "aspects of a Ukrainian settlement" had been discussed.
"While Ukraine has accepted President Trump's ceasefire proposal, Putin continues to show he is more interested in bloodshed than in peace. Targeting innocent civilians as they gather to worship on Palm Sunday is beyond the pale," Republican Congressman Michael McCaul, chairman of the House Committee on Foreign Affairs, said in a post on X.
'Russia Is Targeting Civilians'
Andriy Yermak, Zelenskyy's chief of staff, claimed the missiles contained cluster munitions.
"The Russians are doing this to kill as many civilians as possible," he said, according to Reuters.
Zelenskyy's condemnation of the attack came after a Russian strike on the city of Kryviy Rih killed 20 people, including nine children, just over a week earlier.
Maia Sandu, president of Ukraine's southwestern neighbor Moldova, was quick to offer her condolences, too.
"Palm Sunday is a day of peace. This morning, as people gathered to pray, Russia bombed Sumy -- killing and injuring civilians," she said on X. "Moldova mourns with Ukraine and urges more air defense to save lives. The aggressor must be held accountable. There is no justification for such evil."
There has been no comment yet from the Kremlin on the reported strike.
The UN reported late last month that at least 413 civilians had been killed in the conflict since the beginning of 2025. It also said that more than 2,000 people had been injured in Ukraine due to Russian aggression in the first three months of the year, an increase of 30 percent compared to the same period in 2024.
Ukrainian Foreign Minister Andriy Sybiha said: "For the second month in a row, Russia has refused to accept the US proposal for a full cease-fire, which Ukraine unconditionally accepted on March 11. Instead, Russia ramps up its terror."
"We urge partners to provide Ukraine with additional air defense capabilities and increase pressure on Moscow. Strength is the only language they can understand and the only way to put an end to the horrific terror."
Elsewhere on April 13, the Turkish Defense Ministry said it will hold a meeting on Black Sea security on April 15–16, according to TASS, although Ukrainian officials said such a session had not yet been scheduled.
The meeting would take place in the context of a possible cease-fire between Russia and Ukraine. Military representatives from foreign countries will take part, the Russian news agency reported.
