Kurram is one of the seven autonomous tribal districts bordering Afghanistan where Islamist militants rose up against the Pakistani state in 2004.
Pakistan began a long-awaited push to clear insurgent bases from the North Waziristan tribal district last June after a bloody Taliban attack on Karachi airport finally sank faltering peace talks.
The army has intensified its offensive since the Taliban’s massacre of 153 people, 134 of them children, in a school in the northwestern city of Peshawar in December.
