Human rights groups reacted with alarm Monday to President-elect Barack Obama's intent to wait more than 100 days before emptying the prison camps at Guantanamo Bay, Cuba, and urged him either way to swiftly halt the looming war crimes trial of a Canadian child soldier.

Obama told ABC News Sunday that closing the controversial camps would be complicated. Legal experts, he said, are consulting on how to close the camps that today confine 250 foreign men without risking U.S. national security.

By Monday Obama's transition team said in an anonymous leak to the Associated Press that Obama was preparing to issue an executive order for closing the detention center in his first week in office.
