AM update:

Kyiv (12 p.m.)

The mayor of Kiev said on Sunday that there were no Russian troops in the Ukrainian capital, which was defending itself against attacks.

“But our army, law enforcement and territorial defense continue to detect and neutralize saboteurs,” Vitaly Klitschko wrote on his Telegram channel.

Earlier Sunday morning, a series of explosions were heard west of the center of Ukraine’s capital Kiev on Sunday, minutes after air raid sirens went off, a Reuters correspondent reported.

Ukrainian media reported explosions and a shooting in a nearby town.

According to the Ukrainian news site Segodnya.ua, a bridge exploded near the town of Bucha, west of Kiev.

It was unclear whether it had been shelled by Russian troops or destroyed by the Ukrainian side.

Anton Herashchenko, adviser to the Ukrainian interior minister, said fighting was ongoing in Bucha with Russian forces trying to advance towards Kiev.

A witness in Kharkiv, Ukraine’s second largest city, said Russian soldiers and armored vehicles could be seen in different parts of the city and gunfire could be heard.

Russian forces blew up a gas pipeline, causing a huge mushroom explosion in the night sky.

In the early hours of Sunday, a Russian missile strike landed dangerously close to a radioactive storage facility in Kiev, Ukrainian officials said.

Reports surfaced that a rocket hit the capital’s landfill, but Kyiv officials said the building remained unharmed and the missile actually only landed on the fence around the perimeter.
