The Russian missile attack is carried out from Tu-96 aircraft. More than 30 missiles are expected, said Air Force spokesman Yuriy Ihnat.
"About six Tu-95s have already taken off from the Murmansk Region and launched missiles. We expect more than 30 missiles, which have already begun to appear in different regions, and air defence is working," he said.
Air defence explosions were heard in Kyiv and Vinnytsia regions, and the head of the Lviv Regional Military Administration reported that missiles were moving towards his region.
The massive missile attack began after Russians attacked Ukrainians with attack drones at night.
