A gas explosion in an apartment building Saturday killed at least nine people, including four children, on the island of Sakhalin in far eastern Russia, according local authorities.
A section of the five-story building in the town of Tymovskoye collapsed after a gas cylinder exploded in one of the apartments at around 5:30 am Moscow time, authorities said.
Rescue teams were searching for more victims under the rubble, Sakhalin Governor Valery Limarenko wrote on Telegram. Some of the 33 people known to have lived in the building remained unaccounted for, he said.
Sakhalin is located in the Pacific Ocean, north of Japan.
