Three Pakistani security personnel, who had been injured in an overnight militants attack in the country’s northwest, died Friday, military sources said.

Sources stated that nine security men were injured when over a hundred militants attacked the Police Post in Sarband, an area on the boundary of the restive Khyber tribal region and Peshawar, the capital of Khyber Pakhtunkhwa.

Police said that nine soldiers had been injured when heavily armed militants launched the late night attack. The check post is jointly manned by the paramilitary Frontier Corps and the police.

Police sources said the militants used rocket propelled grenades and automatic weapons in the attack.

Senior Superintendent of Police (SSP) Operations Tahir Ayub said the attack was an apparent reaction to an operation by security forces which had been launched in bordering areas of Khyber Agency on Thursday.

He added that nearly 150 militants launched the attack on the police check post.

No group has claimed responsibility for the attack. Tehrike-e-Taliban Pakistan (TTP) and another militant group ‘Lashkar-e-Islam’ are active in Khyber Agency, also a main NATO supply route to Afghanistan.

However, TTP had warned revenge attacks of its top commander Qari Kamran who was killed with 11 other militants by the security forces in the mountainous Tirah valley on December 31.

The TTP had killed and kidnapped security men to take revenge of the killing of Commander Kamran this month.
