Several explosions were reported around the Ukrainian capital of Kyiv at dawn on Sunday local time.
“A few blasts in the Darnytskyi and Dniprovskyi districts of Kyiv. The services are already working on site. More detailed information later,” said Kyiv Mayor Vitali Klitschko on Telegram.
A journalist who saw the aftermath of the explosions said one north-east of Kyiv sent a thick column of smoke into the sky.
There were also reports of missile strikes around the port city of Odesa early Sunday.
