Los Angeles firefighters injured in explosion of pressurized cylinders aboard truck

LOS ANGELES (AP) — Several Los Angeles firefighters were injured, two critically, when an explosion occurred as they responded to a truck with pressurized cylinders that were on fire. Fire department spokesman Nicholas Prange says an estimated seven firefighters were hurt in the explosion shortly before 7 a.m. Thursday in the Wilmington area. Three firefighters have been taken to a hospital and the others are being evaluated at the scene. Prange told KNX news radio that the cylinders may have contained natural gas. Wilmington is 18 miles south of downtown, near the ports of Los Angeles and Long Beach.
