Immigrants may be held indefinitely

Immigrants arrested in the United States may be held indefinitely on suspicion of terrorism and may not challenge their imprisonment in civilian courts, the Bush administration said Monday, opening a new legal front in the fight over the rights of detainees.

In court documents filed with the 4th U.S. Circuit Court of Appeals in Richmond, Va., the Justice Department said a new anti-terrorism law being used to hold detainees in Guantanamo Bay also applies to foreigners captured and held in the United States.

Ali Saleh Kahlah Al-Marri, a citizen of Qatar, was arrested in 2001 while studying in the United States. He has been labeled an "enemy combatant," a designation that, under a law signed last month, strips foreigners of the right to challenge their detention in federal courts.
