FACTBOX: Six Guantanamo prisoners charged in Sept 11 attacks

(Reuters) - The Pentagon on Monday charged six Guantanamo prisoners for the September 11 attacks on New York and Washington that killed about 3,000 people in 2001.

Each is charged with murder, conspiracy, attacking civilians, terrorism, destruction of property and other crimes. Some also face hijacking charges. The Defense Department is seeking the death penalty against all of them.

The following are is a list of the suspects:

* Khalid Sheikh Mohammed, a Pakistani raised in Kuwait and educated in the United States, has claimed responsibility for 31 attacks and plots including September 11 attacks and the beheading of Wall Street Journal reporter Daniel Pearl. He is accused of serving as military operations commander for all of al Qaeda's foreign operations before his capture in Pakistan in 2003. The Pentagon said he proposed the operational concept of the September 11 attacks to al Qaeda leader Osama bin Laden as early as 1996, oversaw the entire operation and trained the hijackers in Afghanistan and Pakistan.

* Ali Abdul Aziz Ali, also known as Ammar al-Baluchi, is a nephew of Khalid Sheikh Mohammed and cousin of jailed World Trade Center bomber Ramzi Yousef. He is accused of being an important facilitator of the September 11 attacks, transferring money to U.S.-based operatives and assisting nine hijackers on their way from Pakistan to the United States. The Pentagon said he sent about $120,000 to hijackers for their expenses and flight training.

* Mohammed al-Qahtani, who U.S. authorities believe was intended to be one of the September 11 hijackers, was prevented from entering the United States on August 4, 2001, by U.S. immigration officials at Orlando International Airport, where he arrived from the Middle East on a one-way ticket with $2,800 and an itinerary listing a phone number associated with Mustafa Ahmed al-Hawsawi. U.S. authorities say he was planning to meet September 11 hijack ringleader Mohamed Atta and would have been aboard United Airlines Flight 93, which crashed in Pennsylvania during an apparent passenger revolt. Qahtani was captured at Tora Bora in Afghanistan and transferred to the U.S. prison in Guantanamo Bay, Cuba, in February 2002.

* Ramzi Binalshibh, a Yemeni national and one-time roommate of suspected September 11 hijack ringleader Mohamed Atta, is accused of serving as a link between al Qaeda leaders and the hijackers. U.S. officials say he tried but failed to obtain a visa to enter the United States to take part in the attacks as a pilot-hijacker. The Pentagon said he helped find flight schools for the hijackers in the United States. Binalshibh was captured in Karachi in September 2002.

* Mustafa Ahmed al-Hawsawi, a Saudi national, is accused of being a key financial facilitator of the September 11 attacks. The Pentagon said he provided the hijackers with money, Western clothing, traveler's checks and credit cards.

* Walid bin Attash, a Yemeni raised in Saudi Arabia, is accused of running an al Qaeda camp in Afghanistan where he trained two of the September 11 hijackers. The Pentagon said he traveled to Malaysia in 1999 to observe the security of U.S. airlines to assist the hijacking plan. Known by the alias Khallad, he has admitted to planning the attack on the USS Cole, buying the explosives and the boat that was used in the attack and recruiting the operatives. He has also claimed involvement in the bombing of the U.S. embassy in Kenya, saying he was the link between al Qaeda leader Osama bin Laden and the chief of the militant network's Kenya cell.
