Another 21 people were wounded, Donetsk governor Vadym Filashkin said.
Following the latest attack, the Ukrainian president called for Kyiv’s allies to increase pressure on Moscow to end its war in Ukraine.
The bomb hit the village of Yarova in the Donetsk region, Mr Zelenskyy said in a post on Telegram, adding that the attack was “directly on people. Ordinary civilians”.

Yarova is less than 10km from the front line, and was occupied by Russia in 2022 before being liberated by Ukraine’s armed forces in a counteroffensive later the same year.
Mr Zelenskyy posted video footage of bodies on the ground amid debris on Telegram.
“Frankly brutal,” he said, urging the international community to make Russia pay economically for its invasion through additional sanctions.
“The world must not remain silent,” Mr Zelenskyy added. “The world must not remain idle. A response is needed from the United States. A response is needed from Europe. A response is needed from the G20.”

With US-led peace efforts seemingly making no headway, Russia has escalated its attacks on Ukraine. On Sunday, it hit Kyiv with the largest aerial barrage since the war began in February 2022.
