The Pakistani Army has said two members of the security forces and eight militants have been killed in two separate clashes.
In a statement on March 17, the army said soldiers carried out a raid in the Chilas district in the northern Gilgit-Baltistan region, killing three militants.
It said the exchange of fire also killed two security personnel.
The army said another five militants were killed when soldiers returned fire as they attacked a checkpoint in the Khyber tribal region, one of seven agencies along the border with Afghanistan.
The conflict zone is off-limits to journalists, making it difficult to verify the army's claims
The clashes came a day after a bomb blast killed 17 people on a bus carrying government employees in the northwestern city of Peshawar.
Lashkar-e-Islam, a militant group allied with the Pakistani Taliban, claimed responsibility for the attack.
