Firefighters in Antioch late Friday were battling a four-alarm apartment fire, which has sent three people to the hospital with smoke inhalation.
The blaze was first reported at about 10 p.m. in the 3900 block of Delta Fair Boulevard, Contra Costa Fire Protection District Capt. George Laing said.
Four people were treated at the scene for smoke inhalation and three were taken to the hospital.
The blaze may have been started by fireworks, as there were earlier reports of fireworks in the area, according to Laing.
No other information was immediately available.
