Planned outages in force across Ukraine while Russian strike kills 12 miners hours after Zelenskyy says next trilateral talks to start on Wednesday. What we know on day 1,440

A Russian drone strike on a bus carrying miners killed at least 12 people, Ukrainian officials said on Sunday, hours after President Volodymyr Zelenskyy announced new peace talks amid uncertainty over a Russian suspension of attacks on energy infrastructure. First deputy prime minister Denys Shmyhal said the strike in the south-eastern Dnipropetrovsk region was a “cynical and targeted” attack on energy workers. The bus was driving about 65km (40 miles) from the frontline, police said.

A second round of talks between Russian, Ukrainian and US officials on a US-drafted plan to end the war did not go ahead on Sunday in Abu Dhabi as scheduled and Zelenskyy said it would instead take place this Wednesday and Thursday. Ukraine was ready for “substantive” talks, he said. He did not give a reason for the delay, and neither Moscow nor the US confirmed the new dates. Russia has continued attacking Ukraine throughout the negotiating process.

An earlier drone attack in the region overnight killed a man and a woman in the central city of Dnipro, regional military administration head Oleksandr Ganzha said in a post on Telegram. A drone also struck a maternity hospital in the southern Zaporizhzhia region on Sunday, wounding at least seven people including two women receiving a medical examination.
