Reuters correspondents in and around Kyiv said they heard several loud explosions and that air defence missiles were flying overhead.

Emergency power outages began in Kyiv, a local energy provider said.

"[Missiles] Hit one of the capital's infrastructure facilities. Stay in shelters! The air alert continues," Kyiv Mayor Vitali Klitschko wrote on the Telegram messaging app.

He gave no details of what infrastructure was hit. But Russian forces have increasingly targeted Ukrainian critical infrastructure in recent weeks as they faced setbacks on the battlefield following their February 24 invasion.
