PESHAWAR: At least 31 militants were killed late Saturday during air strikes by Pakistani fighter jets in the country’s restive northwest, the military said on Sunday as local troops pressed a six-month offensive in tribal regions along the Afghan border that have long been insurgent havens.

The attacks destroyed four militant hideouts and a suicide bomber training center, said an army statement. The military said several would-be suicide bombers were among the dead, without providing further details.

The military says the operation in Khyber is aimed at militants who have fled a massive offensive in the neighboring North Waziristan region that was launched on June 15, 2014. The army says the offensive has resulted in the killing of 1,200 militants.

The military has been targeting Taleban and Lashkar-e-Islam militants in the region since October.

“Four terrorist hideouts and a suicide bomber training centre were destroyed. 31 terrorists including some suicide bombers were killed,” a statement said.
