A34 closed following multiple-vehicle crash

A large stretch of a dual carriageway is closed following a serious crash involving multiple vehicles, including a lorry.

Thames Valley Police said the the southbound A34 was likely to remain closed for several hours between Didcot and Chilton while investigations are under way.

The northbound carriageway had been temporarily closed to allow an air ambulance to land - but it has now reopened, National Highways said.

Hampshire and Isle of Wight Air Ambulance confirmed that a team of two doctors and a specialist paramedic had been deployed to the incident.
