Nearly 700 drones and 19 missiles struck cities across the country overnight, killing 16 people, officials said. Ukraine's capital, Kyiv, was among the hardest hit.

​On May 4, Russia's attacks killed at least 14 people, Ukrainian officials reported; close to 60 others were wounded. The heaviest toll was reported in Merefa, a town near Kharkiv, where a Russian strike killed seven civilians and injured 32, destroying shops and setting cars ablaze.

Ukraine attacked ​one of Russia's biggest oil refineries on ‌Tuesday, sparking a fire in an industrial area of Kirishi town in the Leningrad region, Governor Alexander Drozdenko ​said.

At least 12 people were killed in Zaporizhzhia, one of the highest tolls from a single attack so far this year. The cities of Dnipro and Kramatorsk were also attacked.

Zelenskyy rebuked Moscow for what he said was its "utter cynicism" in launching the attacks after Russia announced a unilateral ceasefire over two days later this week.
