Emergency teams are dispatched after hearing explosions in the Ukrainian capital.

Three explosions have been heard in the heart of Kiev as Ukraine claims to have shot down several Shahed drones built in Iran.

Mayor Vitali Klitschko reported that rescue services had been sent to the Shevchenkivskyi district in the center of the country after 10 Shahed drones had been shot down by Ukrainian air defenses.

He added on his Telegram channel, "Details later." Klitschko's assertion could not be independently verified.

A Ukrainian politician named Oleksiy Goncharenko claimed on Twitter that by 6.30 a.m. local time, he had heard three explosions (04:30 GMT).

At 5:55 a.m. (03:55 GMT), the air-raid alert had sounded, and locals had been advised to seek shelter until the situation had been resolved.

Goncharenko argued that explosions, not alarm clocks, are what cause Ukrainians to wake up. "Thanks to the close-by Russia! Happy morning!

Oleksiy Kuleba, the governor of Kyiv Oblast, reported that air defense systems were activated and "striking targets."

The explosions occurred as Ukraine requested more sophisticated air defense systems from its partners to assist it in shooting down Russian missiles and drones that had destroyed the nation's energy infrastructure and left millions without heat throughout the bitterly cold winter.

Other areas with "extremely serious" power supply issues, according to Zelenskyy, include the nation's capital Kyiv and the Kyiv region, as well as four regions in western Ukraine and the Dnipropetrovsk region in the country's center.

According to reports on Tuesday, the US was preparing to deploy Ukraine its advanced Patriot air defense system.
