Mayor Kyiv says, explosions were heard early on Wednesday in Kyiv, the capital of Ukraine.
Blasts reportedly shook the Shevchenkivskyi district in the city’s centre, and emergency services were called in, according to Vitali Klitschko.
Oleksiy Kuleba, the governor of Kiev, claims that air defence systems are in operation.
A short time after the air raid siren sounded, BBC reporters heard loud explosions. Since October, Russia has repeatedly used missiles and drones to attack Ukraine’s energy infrastructure.
Serhiy Popko, the head of the military administration for Kyiv, claimed that early on Wednesday, Ukrainian forces had shot down 13 Shahed drones made in Iran.
The body also said a drone fragment had hit two administrative buildings in the city centre. But a spokesperson for the city emergency services told Ukrainian media that no victims had been reported in the strike.
Ukraine has accused Iran of supplying Russia with “kamikaze” drones used in deadly attacks on 17 October, which Tehran initially denied.
Iran later admitted sending Moscow a limited number of drones “many months” before the war.
In response, Ukraine’s President Volodymyr Zelensky said this was a lie and that many more Iranian drones were being used.
Kyiv governor Kuleba said: “The air defence system is operating. It’s important now to stay in shelters and safe places. Russia is continuing its energy terror against our country. But we are getting stronger daily.”
Russia has been targeting Ukraine’s energy grid in recent months in a bid to demoralise its population.
Global leaders have said the strikes civilians infrastructure amount to a war crime, but last week Russian President Vladimir Putin defended the attacks and said they were in response to blast on the Russian bridge to annexed Crimea on 8 October.
