Stepping up action against militants following the recent wave of terror across the country, Pakistan Army destroyed four training camps of Jamaatul Ahrar, a breakaway faction of the banned Tehreek-e-Taliban Pakistan, on the Pakistan-Afghanistan border late Friday night.The outlawed group maintains safe havens across the border in Afghanistan.According to sources, the terrorists were targeted on the opposite side of the Mohmand and Khyber agencies.The camp of Jamaatul Ahrar deputy commander Adil Bacha and a training compound of the group was also decimated, sources said, adding that there were reports of casualties as well.Thirteen people were killed and 85 injured when a suicide blast shook Lahore's Mall Road on Monday. Jamaatul Ahrar had claimed responsibility for the attack.The action came hours after army chief General Qamar Bajwa said terrorists from Afghanistan were carrying out attacks in Pakistan with impunity, adding that “such terrorist activities and inaction against them are testing our current policy of cross-border restraint”.[brid video="114499" player="7247" title="Army decimates four training camps of Jamaatul Ahrar on PakAfghan border"]
