KYIV, Ukraine (AP) Waves of explosives-laden suicide drones struck Ukraines capital Monday, setting buildings ablaze, tearing a hole in one of them and sending people scurrying for cover or trying to shoot them down in what the president said was Russias attempt to terrorize civilians.

The concentrated use of the kamikaze drones was the second barrage in as many weeks after months in which air attacks had become a rarity in central Kyiv. The assault sowed fear and frayed nerves as blasts rocked the city. Energy facilities were struck and one drone largely collapsed a residential building, killing four people, authorities said.

Intense bursts of gunfire rang out as the Iranian-made Shahed drones buzzed overhead, apparently as soldiers tried to destroy them. Others headed for shelter, nervously scanning the skies. But Ukraine has become grimly accustomed to attacks nearly eight months into the Russian invasion , and city life resumed as rescuers picked through debris.
