Six killed in blast in police vehicle in Pakistan

DERA ISMAIL KHAN, Pakistan (Reuters) – Six people,
including three policeman and two paramilitary troops, were
killed in an explosion in a police vehicle in northwest
Pakistan on Sunday, police and witnesses said.

It was not immediately clear what caused the blast as the
police vehicle was patrolling near the town of Dera Ismail
Khan. The town is near the troubled South Waziristan tribal
region, where security forces have been battling al
Qaeda-linked militants and their local supports over the past
two years.
