Russian drone strikes have killed at least two people in Zaporizhzhia and left most of a northern region without power, Ukrainian officials have said.
The news comes as a Ukrainian delegation makes its way to the US for a meeting on restarting peace talks.
Ivan Fedorov, a regional official in Zaporizhzhia, said a man and a woman were killed in the Russian drone strike on Saturday morning.
Two children were also injured in the attack, which struck a private home.
Images posted on Mr Fedorov's official Telegram channel show a house in ruins and a car damaged.
Elsewhere, governor of the Chernihiv region, Viacheslav Chaus, said that most of his region, which borders Belarus and Russia, had been left without power on Saturday after a separate Russian drone attack.
He said repair works were underway to fix the damage.

Talks between US and Ukrainian delegates are expected to take place in Miami later on Saturday, according to Ukrainian state media.
Ukrainian President Volodymyr Zelenskyy said on X on Friday that Kyiv wants "clear dates" for a proposed trilateral meeting with US and Russian representatives.
He added: "Dialogue with the American side must continue in close coordination, because the easing of sanctions by the United States on Russian energy creates risks.
"This increases Russia's revenues and, accordingly, Russian capabilities on the frontline. This is dangerous. Therefore, from this perspective as well, the meeting in the United States is important."
The Trump administration eased sanctions on Russian oil earlier this month as US-Israeli strikes on Iran sent the oil price soaring.
The White House did not confirm any meeting with the Ukrainian delegation, according to the Associated Press news agency.

Kremlin spokesman Dmitry Peskov suggested, however, on Friday that a new round of US-mediated negotiations might take place.
"The pause is temporary, we hope it's temporary regarding the continuation of the trilateral format," he said.
