ISLAMABAD, Oct. 15 (Xinhua) -- Explosions hit a military check post in Pakistan's northwest tribal area of Kurram Agency on Sunday morning, leaving at least four soldiers killed and two others injured, local Urdu media reported.
The explosions were reportedly triggered by about three landmines at the check post in the semi-autonomous Kurram Agency located along Pakistan-Afghanistan border, according to the Dawn.
Security forces cordoned off the area and kicked off a search operation to hunt down the attackers. The injured were shifted to a nearby hospital.
No group or person has claimed the attack yet.
The blast came a few days after the Pakistani army recovered a Canadian-American family in the agency from the custody of Taliban militants who entered from Afghanistan.
