Pakistan’s army says its warplanes have killed 31 radicals as part of an ongoing operation in a troubled tribal region near the Afghan border.

An army statement says the airstrikes on Friday evening in the Tirrah valley of the Khyber region destroyed four rebel hideouts and a suicide bomber training center.

The army says it has killed over 1,200 radicals since a massive offensive launched June 15, 2014 in North Waziristan, another rugged tribal region along the border.

A parallel operation is taking place in neighboring Khyber to pursue radicals fleeing from North Waziristan. Last month’s school massacre in Peshawar — in which 150 people were killed, mainly children — is believed to have been launched from Khyber. SAPA
