Ahmad Sa'id al-Kadr, or Abu Abdurrahman, operated the Afghanistan branch of Human Concern International, a Canadian-headquartered charity.
The report said Kadr was detained by Pakistani police in connection with the November 1995 bombing of the Egyptian Embassy in Islamabad. During Kadr's prison stay, Canadian Prime Minister Jean Chretien was on a state visit to Pakistan and discussed Kadr's case with then-Prime Minister Benazir Bhutto.
Kadr was released a short time later and joined bin Laden in Afghanistan, The Post said.
The list of al Qaida members most wanted by the United States names nine Arabs -- five Saudis and four Egyptians.
Osama bin Laden, blamed by the United States for masterminding the Sept. 11 attacks against New York and Washington, D.C., heads the list. He is followed by Ayman Zawahiri, an Egyptian physician whom U.S. investigators consider to be bin Laden's second in command
The list next names Muhammad Atef, a former Egyptian police officer who was a top aide to Zawahiri in Egyptian Islamic Jihad.
Two other suspects whom little is known other than their Saudi nationality are Abdul Hadi and Saqr Jaravi, the report said. Bilal bin Marwan, another Saudi named on the list, is said by U.S. investigators to be a senior bin Laden lieutenant, but little else is known about him.
