Pakistan's military says troops have killed four Islamic militants during a shootout in the country's north.
Army officials say Friday's clash erupted after militants attacked an army convoy in the tribal region of North Waziristan.
In a statement, the Pakistani army says the rebels opened fire on the approaching convoy after detonating a roadside bomb which failed to do any damage.
Troops fired back, killing four militants.
Also on Friday, nearly one thousand tribesmen rallied in Miran Shah, protesting government operations and demanding the withdrawal of army checkpoints in the region.
Deadly violence and unrest have risen in Pakistan since July when security forces raided an Islamabad mosque controlled by Islamist radicals. The assault left more than 100 people dead.
