Russia has launched about 110 missiles overnight as well as drones against Ukrainian targets in one of the biggest barrages of the year, Ukraine President Volodymyr Zelensky said.

Most of the incoming missiles and drones were shot down, but at least seven civilians were killed and an unknown number of people were buried under rubble, Ukrainian officials said.

Scores of people are reported to have been injured.

Mr Zelensky said the Kremlin’s forces used a wide variety of weapons, including ballistic and cruise missiles.

Ukrainian air force spokesman Yurii Ihnat said Russia “apparently launched everything they have” against targets across Ukraine.

The roughly 18-hour onslaught that began on Thursday and continued through the night hit six cities, including the capital Kyiv, and other areas from east to west Ukraine, according to authorities.
