Pakistan summons Iran envoy after six troops killed in militant attack near border

Pakistan's foreign ministry says it has summoned Iran's ambassador following the killing of six paramilitary troops who were ambushed by militants while patrolling the border.

Pakistan has lodged a complaint with Iran and demanded that its neighbour take action against the armed group responsible for the ambush. No one has claimed the attack, and neither country has identified those responsible.

Some 30 militants attacked the Frontier Corps convoy on Friday, killing six soldiers and wounding 14. Four attackers were killed in the shootout.

Iran condemned the attack on Saturday and vowed to cooperate with Pakistan.

A number of militant groups as well as drug smugglers operate in the border region.

Militants captured around a dozen Iranian border guards near the border in October. Five were released in Pakistan last month, under unclear circumstances.
