A petrol bomb hurling mob forced two Cabinet ministers touring floodravaged Pakistan to be airlifted to safety.
A five-car convoy carrying Development Secretary Andrew Mitchell and Tory Party Chairman Baroness Sayeeda Warsi was caught up in a violent demonstration against fuel price increases.
Witnesses said the convoy was pelted with petrol and stones before being re-routed to a nearby airbase. The group were later flown out of the area in an army helicopter.
The ministers, returning to the capital Islamabad, were attacked near the town of Nowshera in a region known for its links to the Taliban.
A Foreign Office spokeswoman said: "The ministerial party was re-routed to avoid a large, ongoing public protest as a precaution and are now continuing their programme."
