Russian air strikes have hit cities across Ukraine, including the capital Kyiv, killing at least five people.
Ednews reports citing BBC that a woman and a three-year-old child were killed in the city of Dnipro, according to the local mayor.
Three people died in Uman after missiles hit residential buildings, officials said. A nine-storey apartment building there was badly damaged.
There were also explosions in the cities of Kremenchuk and Poltava, according to the Interfax news agency.
In Kyiv, 21 out of 23 missiles and two attack drones were shot down by Ukraine's air defence system, officials said in a Telegram post.
The head of the Kyiv city military administration said this was the first Russian missile attack on the capital in 51 days.
There are no immediate reports of civilian casualties in the capital.
The attacks come as Ukrainian forces are believed to be preparing for a military offensive with new equipment, including tanks, supplied by Western allies.
Russia has struggled to make headway in a winter offensive including a 10-month battle for control of the strategically important eastern city of Bakhmut.
