MIAMI (Reuters) - Prosecutors in the Guantanamo war crimes tribunals have filed new terrorism charges against a Saudi prisoner accused of plotting with al Qaeda to blow up oil tankers off the coast of Yemen, the Pentagon said on Wednesday. Ahmed al Darbi could face life in prison if convicted on six charges that include conspiracy, aiding and abetting the hazarding of a vessel and aiding and abetting terrorism. Darbi, 37, is accused of working as a weapons instructor at an al Qaeda camp in Afghanistan in the late 1990s and meeting al Qaeda leader Osama bin Laden there. He also is charged with abetting a plot to bomb civilian tankers in the Strait of Hormuz and off the coast of Yemen from 2000 to 2002.

Specifically, he is accused of using al Qaeda money to buy a boat and GPS navigational devices and helping obtain travel documents for al Qaeda operatives. He also is accused of abetting the plot to bomb a French oil tanker, the MV Limburg, off Yemen in 2002. The blast killed a Bulgarian crewman and dumped tens of thousands of gallons of oil into the Gulf of Aden. “Mr. al Darbi’s alleged crimes are serious violations of the law of war that were committed to terrorize and wreak havoc on the world economy,” Brigadier General Mark Martins, the chief prosecutor for the Guantanamo tribunals, said in a statement. Darbi’s lawyer did not immediately respond to a request for comment on Wednesday.
