SAN'A, Yemen - A Yemeni judge sentenced two men to death and four others to prison terms ranging from five to 10 years Wednesday for orchestrating the 2000 suicide bombing of the USS Cole, an attack blamed on Osama bin Laden's terror network.

Saudi-born Abd al-Rahim al-Nashiri, who is in U.S. custody at an undisclosed location, and Jamal al-Badawi, a 35-year-old Yemeni, were both sentenced to death for plotting and involvement in the bombing, which killed 17 American sailors as their destroyer refueled in the southern Yemeni port of Aden.

Al-Nashiri, believed to be the mastermind of the Oct. 12, 2000 bombing, was the only one of the six defendants not in the heavily guarded court to hear the sentences. The other five defendants are all Yemenis.

The United States announced al-Nashiri's arrest in 2002. He was detained in the United Arab Emirates and transferred to American custody. U.S. officials believe he is a close associate of Saudi-born bin Laden, who is believed to have masterminded the Sept. 11, 2001 attacks.

In addition to the Cole attack, al-Nashiri is suspected of helping direct the 1998 bombings of U.S. embassies in Kenya and Tanzania.

The six men were all charged with belonging to al-Qaida and playing various roles in the attack on the Cole, which was carried out by suicide bombers Ibrahim al-Thawr and Abdullah al-Misawa, both Yemenis, who rammed an explosives-laden boat into the destroyer.

Judge Najib al-Qaderi sentenced Fahd al-Qasa to 10 years in jail for filming the bombing, which left a gaping hole in the side of the destroyer, which was later repaired and returned to service.

The court has heard that al-Qasa had traveled to Afghanistan in 1997 to train at an al-Qaida terrorist camp, but it was unclear how long he spent there before returning to Yemen, a tribal-dominated country located at the southern tip of the Arabian Peninsula.

Maamoun Msouh received an eight-year prison term for delivering money used in preparing and executing the attack and playing a close role in assisting al-Badawi.

Ali Mohamed Saleh and Murad al-Sirouri were both sentenced to five years in prison for forging identification documents for al-Misawa, one of the suicide bombers.
