A political secretary and his security guard were shot dead by unidentified assailants in Kurram Agency on Sunday, political administration officials said.

The secretary, Sarfraz Hussain and his guard were travelling in a vehicle in Kurram Agency's Walicheena area when the suspects opened fire and killed them, the officials added.

Officials of the political administration and security forces surrounded the area following the incident and the bodies of both the victims were transferred to headquarter hospital in Kurram.

A few weeks ago, two census workers were injured along with nine others when the van in which they were travelling hit a landmine in Godar area of Kurram Agency.

In the same incident, 14 others were killed, including five women and four children.

While the banned extremist group Lashkar-i-Jhangvi claimed responsibility for the incident, the political administration said it was a matter of personal enmity. The administration also announced to have arrested a person in connection with the double murder.
