A US news helicopter crashes near the scene of a fatal bus accident in Los Angeles, killing at least three people and bursting into flames, according to multiple outlets citing officials. One additional person is reported as taken to hospital, though details of injuries vary by report.

Several sources say the helicopter comes down in or near a parking lot between or beside vehicles, while crews were covering the bus collision in the Chatsworth area of the San Fernando Valley. The bus accident involves an SUV and a city bus, leaving at least two people dead and multiple others injured. Outlets describe different information about the exact crash location and whether the helicopter is associated with NBC Los Angeles, but they broadly agree the helicopter is conducting aerial coverage when it crashes.

Officials quoted by different outlets say the connection between the helicopter crash and the bus accident is not immediately clear, while reporting consistently places the incidents near each other and links the helicopter’s presence to coverage of the bus collision.
