A Russian drone strike on the major Ukrainian city of Kharkiv killed four people and wounded 17 on Sunday, its mayor said. “At this moment, 17 people are known to have been wounded. Four people have died,” Igor Terekhov said, reporting the evening strike in a message on Telegram. The attack came as US, Ukrainian and European officials were in Geneva to discuss a proposal to end the nearly four-year-old war in Ukraine.

Oleg Synegubov, head of the Kharkiv regional military administration, described the attack as “massive”. The emergency services said the drone strike on two districts of Kharkiv had caused fires and the destruction of buildings. “Three residential buildings and an infrastructure facility were on fire,” it said.

Top US and Ukrainian officials said on Sunday they had made progress towards ending the Russia-Ukraine war but provided scant details after discussing the American proposal to achieve peace that has sparked concerns among many of Washington’s European allies that the plan is too conciliatory to Moscow. US secretary of state Marco Rubio said high-stakes talks in Geneva were “very worthwhile” and constituted the most productive day in “a very long time”. “I feel very optimistic that we can get something done.”
