At least 20 soldiers have been killed when a bomb blast hit an army convoy in north-western Pakistan, officials say.
More than twenty others were injured in the attack in the north-western region of Bannu, and there are fears that the death toll will rise further.
Unconfirmed reports say the attack was carried out by a suicide bomber.
Although no group has so far claimed responsibility for the explosion, the Pakistani Taliban recently vowed to increase attacks on security forces.
