Ukraine's army said Friday that it repelled an overnight drone attack on the country, including on the capital Kyiv, a day after Russia launched a barrage of missiles on the war-battered nation.
"On the night of December 29-30, the enemy attacked Ukraine with Iranian-made kamikaze drones," Ukraine's air force said in a statement on social media.
In the capital Kyiv, the city authorities announced an air alert at 2:12 am local time (2412 GMT), which lasted for just over two hours.
Mayor Vitali Klitschko later said the capital was attacked with seven drones: two were shot down "on approach" and five over the city.
There were no casualties, but falling debris damaged windows in two buildings in a southwestern neighbourhood, he added.
On Thursday morning, blasts were reported across Ukraine -- including in Kyiv, the second city Kharkiv in the east and the western city of Lviv near the border with Poland.
Ukraine's army said Russia had launched 69 cruise missiles, 54 of which had been shot down.
Ukraine's President Volodymyr Zelensky said most regions were left without power following Thursday's attack.
