Powerful explosions rocked the Ukrainian city of Mykolaiv early on Saturday, the mayor said, a day after authorities said at least 21 people were killed when Russian missiles struck an apartment building near the Black Sea port of Odesa.
Walls and windows of a neighbouring 14-storey apartment block were damaged by the blast wave. Nearby holiday camps were also hit.
The region will observe a day of mourning on Saturday for those killed during the attack, Bratchuk said. He posted a video of what he said was the attack. Reuters could not confirm the authenticity of the video or the Russian action depicted. There was no immediate Russian comment. Putin met the president of Indonesia on Thursday and spoke by phone on Friday to the prime minister of India, promising both major food importers that Russia would remain a big supplier of grain.
Moscow has been on the verge of capturing Luhansk since taking the city of Sievierodonetsk last week after some of the heaviest fighting of the war.
