Kabul: Multiple explosions ripped through the Ukrainian capital Kiev in the rush hours of Monday morning, according to local officials.
Sirens were heard moments before the first explosion at around 6:35 am local time (0335 GMT), followed by sirens across the country, reports said.
“The capital was attacked by kamikaze drones,” Ukrainian president’s chief of staff Andriy Yermak said. “We need more air defense systems and as soon as possible. We have no time for slow actions. More weapons to defend the sky and destroy the enemy.”
Local media also reported strikes in Sumy Oblast in north-east Ukraine as well as Dnipropetrovsk in the south-east, where a fire broke out at an energy facility after it was hit by a missile.
The strikes on Monday come a week after a series of missiles hit Kiev and other cities across the conflict-battered country, leaving dozens dead.
The air raid on October 10 was in response to a powerful blast that targeted a bridge connecting the Russian mainland to the Crimean Peninsula.
The explosion on October 9 set fire to seven oil tankers that were being carried by rail to Crimea, sparking a massive blaze and killing at least three people.
Russia’s Federal Security Service (FSB) accused Ukraine’s military intelligence service and its director, Kyrylo Budanov, of organizing the attack, with a Kiev agent reportedly coordinating the transit of the explosives.
Putin, who dubbed the Crimea bridge blast a “terrorist act” carried out by Ukraine’s secret services, vowed to react forcefully if such attacks continued.
