Pakistani military said on Wednesday its security forces killed 12 suspected Taliban militants during a major anti-insurgent operation in a tribal village bordering Afghanistan.
Security forces were acting on intelligence that militants had gathered in Tor Chaphar, a village on the outskirts of the lawless northwestern town of Darra Adam Khel Bazaar, and were preparing an attack, said the military.
Darra Adam Khel witnessed heavy fighting last year when militants occupied a Japanese-built tunnel, blocking traffic between Peshawar, the capital of North West Frontier Province, and the garrison city of Kohat.
The military's media department said security forces armed with heavy artillery pounded suspected hideouts on Tuesday and killed 12 militants.
The troops suffered no casualties, a statement said.
It was not possible to confirm the military statistics independently.
Darra Adam Khel is infamous for its weapons bazaar and illegal arms factories. It became a stronghold of the banned Sunni Muslim extremist group, Lashkar-e-Jhangvi, which has links to Al-Qaeda, security officials said.
More than 50 militants were killed in an operation in January 2008 when Pakistan artillery, backed by gunship helicopters, tried to dislodge militants from bunkers built into hills overlooking the Kohat tunnel.
