Greater Manchester police say that a large explosion and a fire have taken place in an apparent terror incident on the M62 near junction 12.
The explosion happened in the taxi after the vehicle struck a police patrol vehicle in the early hours of Tuesday morning.
Greater Manchester Police say the device was a homemade bomb and that counter terrorism officers have taken control of the incident.
In a statement, the police force said one man is in hospital in a serious condition. They say the cabbie is in a “fairly critical” condition and that the area is cordoned off.
Greater Manchester police said the public should avoid the area and all roads are closed.
British Transport Police said that they are “monitoring the situation” and “stand ready to provide assistance”.
Eyewitness Jonnie Simpson, who is walking along the M62, said he saw one injured person being treated on the side of the road outside an Asda store.
He said he was carrying out a normal walk when he looked up and saw the explosion.
“I looked up to see a truck on fire and I thought ‘oh god, is it going to explode?’
“I got back on the road and was shocked to see first responders, police officers and other emergency personnel all around my car. “
In London, Metropolitan Police say that it is aware of an incident on the motorway, but there are no immediate reports of injuries.
