The Northern Ireland police service said the vehicle crashed a short distance away. The violent crowd was trying to get close to a loyalist bonfire near the motorway, said the force. Petrol was thrown at officers in North Queens Street where around 40 people have gathered, it added. Meanwhile in north Belfast there are unconfirmed reports of shots being fired close to the Ardoyne district.
