A lorry driver has been arrested after 19 people were injured, six of them seriously, in a crash with a minibus in West Yorkshire.
The collision happened on the westbound carriageway of the M62 near Pontefract at around 11.30am.
Rescuers are working to free those who remain trapped, West Yorkshire Police said.
The minibus was believed to be carrying a group of around 20 women, all from the West Yorkshire area.
Emergency services - including six air ambulances - were called at 11.30am to junction 32 of the M62 after the crash near the Xscape leisure park.
Police said the incident had left the motorway closed in both directions and advised motorists to avoid the area.
A Police spokesman said the driver of the lorry, a local man, has been arrested in connection with the incident.
Kevin Hodgson, director of operations at Great North Air Ambulance, said they had sent two air ambulances, which were joined by two from North West Air Ambulance and another two from Lincolnshire and Nottinghamshire Air Ambulance.
He said one had taken a casualty to Leeds General Infirmary while another was en route to the James Cook University Hospital in Middlesbrough with a patient on board.
