Serhiy LysakNine people have been killed after a Russian drone hit a bus transporting workers in Ukraine, officials say.
The attack occurred on Wednesday morning in the south-central city of Marhanets.
Serhiy Lysak, regional chief of Dnipropetrovsk, said at least 30 people were injured, adding that "the number of victims is constantly growing".
The attack comes as diplomats from the UK, France, Germany, the US and Ukraine are preparing to hold talks in London aimed at securing a ceasefire in the conflict.
Russia launched a full-scale invasion of Ukraine on 24 February 2022. It is estimated that hundreds of thousands of people have been killed or injured on all sides since then.
Russian President Vladimir Putin declared a 30-hour ceasefire for Easter Sunday. Ukraine said it mirror Russia's actions. Each side accused the other of breaking the truce.
Last month, Moscow came up with a long list of conditions in response to a full ceasefire that had been agreed by the US and Ukraine.
The US has been holding talks with Russia and separately with Ukrainian and European officials to broker a truce.
