Osama bin Laden, leader of the al-Qaeda terrorist network, has not been nabbed in Pakistan, Foreign Office spokesman said Monday in Islamabad.

Spokesman Masood Khan told a weekly press briefing that the terror Czar "has not been sighted on Pakistan's soil."

"Media reports speculating on the al-Qaeda leader's capture are baseless," the spokesman noted.

He also shrugged off the assumption that US military personnel have been conducting the operation on terrorists within Pakistan's border.

Sharing an over 2,500-km volatile border with Afghanistan, Pakistan's western tribal belt has long been branded hotbed for the al-Qaeda and Taliban fugitives since the United States launched the anti-terror war in Afghanistan in 2001.
