A federal judge ordered the release of five Algerian terror suspects held without charges at Guantanamo Bay prison for almost seven years.

In the first civilian court ruling for terror suspects challenging their detention, U.S. District Judge Richard J. Leon said Thursday that the five men could not be held indefinitely as enemy combatants.

Leon ruled that the U.S. government failed to prove that five of the six Algerians held at Guantanamo Bay since Jan. 20, 2002 were enemy combatants headed to Afghanistan to fight against the United States.

The feds’ claim relied on one source, and the government didn’t provide enough evidence to prove that source’s reliability, according to the decision.
