Military spokesman: Clashes break out after militants ambush camp, vehicle

(CNN) —  

Fifteen Pakistani paramilitary troops were killed when militants ambushed their camp in southwestern Pakistan Monday, a military spokesman said.

Attackers fired rockets at the camp and opened fire on a patrol vehicle in the southwestern province of Balochistan, military spokesman Murtaza Beg said.

A senior military official was among those killed, Beg said, and eight troops were injured in the attack.

Militants were also killed in clashes, he said, but authorities were still trying to confirm the casualties.

No one had claimed responsibility for the attack Monday, but authorities suspect militants fighting against security forces in the area are responsible. Paramilitary troops began an operation to search for suspects in nearby mountains, Beg said.

The clashes occurred in the coal-rich Chamalang area of district Loralai, where security personnel are frequently attacked, Beg said.
