Pentagon officials said Wednesday they now believe the al Qaeda terrorist network was connected to an attack in Kuwait that left one U.S. Marine dead and another wounded. They said it appears the two assailants, who were killed by U.S. military police shortly after the attack, had been in Afghanistan, where they were trained in al Qaeda training camps. The two are also believed to have relatives who are being held by the United States at the U.S. Navy base at Guantanamo Bay, Cuba. The officials said they did not know whether the leadership of al Qaeda ordered the attack or whether it was the work of an independent al Qaeda cell. Earlier Wednesday, a top Kuwaiti military official said the two Kuwaitis who killed a U.S. Marine and wounded another on the island of Failaka had affiliations with "certain extremist groups."
