Parachinar: A Pakistani government official says security forces have killed at least 20 militants after coming under attack near the Afghan border.
Wajid Khan says 22 troops were also wounded in Thursday`s gunbattle in the northwestern Kurram tribal region.
He says the fighting began when a group of Pakistani militants attacked a security post. The troops returned fire and killed 20 militants.
The death toll could not be independently confirmed as the fighting was in a remote mountainous area that is off-limits to journalists.
Kurram is considered a main base for the Pakistani Taliban. Scores of insurgents are believed to hiding there after escaping military operations in the nearby tribal regions in recent years.
