The explosion of an apartment building in Bellevue, Washington, killed four people, and injured more than 30 others, including at least one critically, early Wednesday, police said.
The blast took place at a high-rise apartment complex in Bellevues Westside neighborhood, said Bellevue Police Sgt. David Smith.
A person was in the apartment at the time of the explosion, and the injured were taken to Bellevue Hospital, he said.
Smith said authorities were still trying to determine the cause of the fire, which occurred in the building’s courtyard.
