At least 17 Pakistani soldiers have been killed and 11 wounded after a roadside bomb hit a military convoy in a northwestern tribal area, officials said.
The attack happened on Sunday in Dosali village in the North Waziristan tribal district, a stronghold of Taliban fighters.
Nobody immediately claimed responsibility but Taliban fighters frequently attack security force convoys in the area.
The seven northwestern tribal districts are rife with homegrown fighters and are strongholds of Taliban and al-Qaeda operatives.
Islamabad says more than 35,000 people have been killed as a result of “terrorism” in the country since the 9/11 attacks on the United States.
The area has been a sore point in relations between Pakistan and the United States. Washington has repeatedly pushed Islamabad to launch an operation in North Waziristan, especially against the Haqqani network, which is seen as one of the most dangerous groups fighting in Afghanistan. But Pakistan has so far refused.
