PESHAWAR: At least seven personnel of Frontier Corps (FC) were killed in firing from the Afghan side of the border in the Angoor Adda area of South Waziristan Agency early yesterday. Local sources said the firing occurred on an FC checkpost, northeast of Angoor Adda, which killed seven soldiers. “Three other FC personnel were also injured,” a senior military official said in a statement. The injured were shifted to Combined Military Hospital (CMH) Peshawar.

The firing continued for several hours. After the attack the security of areas adjacent to Pak-Afghan crossing point has been enhanced. Earlier on Sunday, at least four soldiers of Pakistan Army were killed and four injured as militants fired rockets from across the Pakistan-Afghanistan border in Khyber Agency. According to reports, the rounds fired from Afghanistan side, opposite Khyber Agency, by terrorists hit 8,000-foot-high Pakistani post in Akhandwala Pass,” the statement added.

It was not confirmed whether the attack was carried out by Taliban insurgents or Afghan forces. The attack was carried out at the time when Taliaban forces have intensified their attacks in Afghanistan also. Soon after the attack, Interior Minister Chaudhry Nisar Ali Khan strongly condemned the killing of Pakistani soldiers in the firing from across the afghan border .

Reuters adds: A military official who declined to be identified said Afghan-based militants were responsible for the attack, which is likely to put more strain on tense relations between the neighbours. In 2011 24 Pakistani soldiers were killed in a NATO air strike on the afghan border that sent tensions soaring, with Islamabad cutting off critical NATO supply routes into Afghanistan and Pakistani officials alleging the US had deliberately targeted their troops at border posts. In June last year the Pakistani army launched a long-awaited offensive against militants in the tribal areas of North Waziristan, where they had previously been operating with impunity. Islamabad and Kabul regularly accuse each other of giving sanctuary to militants.
