A BUS has burst into flames on the Hinksey Hill roundabout. 

Dramatic photos show the purple bus in a cloud of smoke on the interchange. 

Police shared photos of the scene on Twitter saying that traffic was 'flowing fine' in both directions on the A34. 

Firefighters are currently at the scene and cones have closed off slip road. 

Thames Valley Police roads policing added: "The southbound A34 carriageway is starting to slow due to the current road closures. This is forcing more traffic onto the southbound carriageway. The off slip is currently closed on the northbound and access round the roundabout is limited."

It is not yet known how the fire was started or if anybody is injured.
