21 Killed, Over 80 Wounded In Russian Missile Strike On Ukraine's Sumy

At least 21 people were killed and 83 others were wounded by a Russian ballistic missile strike in the heart of the northern Ukrainian city of Sumy on Sunday morning, Ukraine's interior minister Ihor Klymenko said.

President Volodymyr Zelenskiy condemned the attack - one of the deadliest strikes on Ukraine this year - and called for a tough international reaction against Moscow.

"Only scoundrels can act like this. Taking the lives of ordinary people," he wrote on social media, alongside a chilling video which showed corpses on the ground, a destroyed bus and burnt-out cars in the middle of a city street.

"And this is on a day when people go to church: Palm Sunday, the feast of the Lord's Entry into Jerusalem," Zelenskiy said.

Interior minister Klymenko said the victims were on the street, in vehicles, public transport and in buildings when the strike hit.

"Deliberate destruction of civilians on an important church feast day," he wrote.

Reuters was seeking comment from Russian authorities.

Andriy Kovalenko, a security official who runs Ukraine's Centre for Countering Disinformation, noted that the strike came after a visit to Moscow by U.S. envoy Steve Witkoff.

"Russia is building all this so-called diplomacy ... around strikes on civilians," he wrote on Telegram.

Witkoff, U.S. President Donald Trump's special envoy for Ukraine, held talks with Russian President Vladimir Putin on Friday in St. Petersburg on the search for a Ukraine peace deal, as Trump told Russia to "get moving".

In the aftermath of Sunday's strike, Zelenskiy called on the U.S. and Europe to get tough on Russia in response to what he described as terrorism.

"Russia wants exactly this kind of terror and is dragging out this war. Without pressure on the aggressor, peace is impossible. Talks have never stopped ballistic missiles and aerial bombs," he wrote.

Russia launched a full-scale invasion of Ukraine in February 2022 and currently holds about 20% of the country's territory in the east and south. Russian forces have been slowly advancing in the east of late, though missile and drone strikes now dominate the war.

Russia's defence ministry said on Saturday that Ukraine had carried out five attacks on Russian energy infrastructure over the previous day in what it called a violation of a U.S.-brokered moratorium on such strikes.

Ukraine and Russia agreed to pause strikes on each other's energy facilities last month, but both sides have repeatedly accused each other of breaking the moratorium.
