No casualties were reported following explosions Tuesday in the Lviv region in western Ukraine, local officials said.

“Explosions near Radekhiv,” regional governor Maksim Kositsky said on Telegram, referring to a town about 70 kilometres (40 miles) northeast of Lviv. “Everybody must remain in shelters.”

A short while later he said in another post: “As of this hour, there is no information on victims.”

After Russian troops withdrew from the Kyiv region in recent days, Ukrainian officials say they are bracing themselves for a Russian assault in Donbas in eastern Ukraine.
