Ukrainian authorities said 37 missiles and 29 drones have been shot over Kyiv. Meanwhile, Denmark pledged billions more in military aid.
Kyiv has largely fended off a wave of Russian air strikes, officials said on Monday, but later strikes killed several civilians.
Valery Zaluzhny, commander-in-chief of the Ukrainian armed forces, said that Ukraine had managed to shoot down 37 missiles and 29 drones. He said that Russia had launched up to 40 missiles and around 35 drones.
On Saturday night, the city was faced with the largest wave of air strikes since the start of the invasion.
"Only 18 hours have passed since the most massive UAV attack on Kyiv, and the enemy has attacked the capital again," Kyiv's military administration said, adding that this was the fifteenth air raid since the start of the month.
Latter on Monday, two people were killed and eight others were wounded in a Russian attack on the city of Toretsk in the Donetsk region.
"Every day, the Russians purposefully hit civilians in the Donetsk region," the region's governor Pavlo Kyrylenko said.
One woman was killed by shelling in the Dnipropetrovsk region, and one man was killed in an attack in the Kherson region, local authorities said.
Kyiv mayor Vitali Klitschko said that no casualties were reported in the capital and there was no damage to infrastructure.
