Al-Qaeda chief Osama bin Laden is living comfortably in a house in northwest Pakistan. CNN quoting a NATO official says, Osama is being protected by local people and some members of the Pakistani intelligence services. It also said that the Al-Qaeda number two, the Egyptian-born Zawahiri is also living close to him. The reports says, Mullah Omar, the leader of the Taliban, has moved between the cities of Quetta and Karachi in Pakistan over the last several months. Pakistan's mountainous North Waziristan region, which borders Afghanistan, is believed to be a vortex of Afghan, Pakistani and Arab militants, and long held to be a possible hiding place for Osama.However, Pakistani authorities have denied they are providing protection for the terror mastermind. Meanwhile, the spokesman of NATO-led International Security Assistance Force (ISAF) today denied media reports on existence of secret prison allegedly run by U.S. military in the war-torn Afghanistan. Refusing these allegations, Brigadier-General Josef Blotz told reporters, the U.S. force in Afghanistan is running a detention facility in Bagram and it is run jointly by U.S. and Afghan authorities.
