Authorities in Pakistan say they have arrested one of America's most wanted al-Qaida leaders.

Senior Pakistani government officials, speaking on condition of anonymity, say Khalid Shaikh Mohammed was among three people detained. They say he was picked up along with a Pakistani and a man of Middle Eastern origin from a house in Rawalpindi, near the Pakistani capital.

U.S. officials believe Kuwaiti-born Khalid Shaikh Mohammed was a key figure in planning the September 11, 2001, terror strikes on U.S. cities, blamed on the al-Qaida terrorist network. He is wanted by the Federal Bureau of Investigation for his alleged involvement in a conspiracy to bomb commercial airliners in 1995. Washington was offering $25 million for information leading to his arrest.
