Military prosecutors have recently picked up the pace in their effort to try 60 to 80 captives on terrorism charges at the Guantanamo Bay U.S. naval base in Cuba.

Ibrahim Ahmed Mahmoud al Qosi, 47, is one of a dozen prisoners facing charges in the widely criticized Guantanamo court system. He is accused of providing material support for terrorism and conspiring with al Qaeda to attack and murder civilians and destroy property.

The Pentagon official overseeing the Guantanamo war court approved charges on Wednesday, clearing the way for his trial to begin within 120 days.

Qosi was born in Khartoum, a one-time base for bin Laden, and is alleged to have served as a guard, driver and logistics operative for the al Qaeda leader in Afghanistan from 1996 to 2001.

The U.S. military alleges that Qosi provided services and supplies for bin Laden's "Star of Jihad" compound in Jalalabad and for another compound near Kandahar before joining an al Qaeda group that launched mortars in Afghanistan from 1998 to 2001.

Qosi is accused of helping bin Laden and his family flee to the Tora Bora mountains of Afghanistan after the U.S.-led invasion to oust al Qaeda and its Taliban government protectors following the September 11 attacks. He would face life in prison if convicted.

The Pentagon is still reviewing charges that prosecutors filed last month against the alleged planner of the September 11 attacks, Khalid Sheikh Mohammed, and five other Guantanamo prisoners accused of direct involvement in the hijacked plane attacks that killed nearly 3,000 people in 2001. They would face execution if convicted.
