Russian ballistic missiles and drones have been launched toward Ukraine from multiple directions, the Ukrainian Air Force said on Telegram Friday.

Fires caused by falling debris and drone strikes were reported in buildings across Kyiv, as Ukraine attempted to repel the Russian attack, the Head of Kyiv City Military Administration Tymur Tkachenko said. A CNN producer in the Kyiv region reported hearing at least two explosions.

Tkachenko accused Russia of hitting residential areas with the drone attack, saying a high-rise building the the Solomyansky district of Kyiv was damaged.

Kyiv’s Mayor Vitali Klitschko also reported fires in the districts of Holosiivskyi and Darnytskyi of the Ukrainian capital.

Ukrainian air defense units have been activated in the Obolon area of Kyiv, Klitschko said on Telegram early Friday morning local time.

“The attack on the capital continues. Stay in shelters!” the mayor said.

The Russian missile attack on Ukraine comes days after Ukraine’s security service launched a series of daring, large-scale drone attacks deep inside Russia, striking airfields and hitting 41 Russian military aircraft.

On Tuesday, Ukraine also launched an attack on the Kerch Bridge, the only direct connection point between Russia and the annexed Crimean Peninsula, with 1,100 kilograms of explosives that had been planted underwater.

This is a developing story and will be updated.
