Emergency services are treating three children and an adult following a serious crash on the M66 this afternoon.
Two air ambulances, fire crews, paramedics and police have all been deployed to the scene between junction 3 for Pilsworth Road in Hollins to junction 4 for Simister Island.
The motorway has been closed in both directions to allow the air ambulance to land. Footage shows two helicopters landing on the opposite side of the carriageway.
