Fire officials say a Metro Blue Line train has collided with a bus south of downtown Los Angeles injuring at least 13 people.

Los Angeles Fire Department spokesman Brian Humphreys says it is unclear how the accident happened. Humphreys says most of the injuries appear to be minor.

The crash comes one week after a Metrolink train smashed into a freight train in the San Fernando Valley, about 30 miles northwest of downtown.
