Missiles launched from Belarus had hit an airport in Zhytomyr in northern Ukraine on Sunday, an adviser to Ukraine’s interior minister said.
Ukrainian and Russian officials are due to meet for talks at a venue on the Belarusian border with Ukraine, President Volodymyr Zelenskiy’s office said earlier.
Anton Herashchenko, the adviser to Ukraine’s interior minister, had earlier said that Iskander missiles were launched at Ukraine from Belarus at around 5pm local time.
The mayor of Kyiv said on Sunday there were no Russian troops in the Ukrainian capital, which was holding its defence against attacks.
“But our military, law enforcement and territorial defence continue to detect and neutralize saboteurs,” Vitaly Klitschko wrote on his Telegram channel.
Earlier on Sunday morning, a series of blasts was heard to the west of the Ukrainian capital Kyiv’s centre on Sunday, minutes after air raid sirens sounded, a Reuters correspondent reported.
Ukrainian media reported explosions and a gunfight in a nearby town.
According to Ukrainian news website Segodnya.ua, a bridge has been blown up near the town of Bucha west of Kyiv.
It was unclear whether it had been bombed by Russian troops or destroyed by the Ukrainian side.
Anton Herashchenko, an advisor to Ukraine’s interior minister, said fighting was under way in Bucha with Russian forces that were trying to advance towards Kyiv.
A witness in Kharkiv, Ukraine’s second-largest city, said Russian soldiers and armoured vehicles could be seen in different parts of the city and firing could be heard.
Russian forces blew up a gas pipeline, causing a huge mushroom explosion to fill the night sky.
In the early hours of Sunday, a Russian missile strike landed dangerously close to a radioactive storage facility in Kyiv, Ukrainian officials said.
Reports emerged that a rocket had struck the waste disposal site in the capital but officials in Kyiv clarified that the building was left unscathed and the missile had in fact only landed on the fence around the perimeter.
