WASHINGTON (AFP) - The Guantanamo camp may have only 30 to 40 "real" cases and the US detention center should be shut down by 2007, the president of the Belgian Senate, who headed a European inspection team there, said.

Presenting her findings in Washington on behalf of the Organization for Security and Cooperation in Europe (OSCE), Anne-Marie Lizi recommended the shutting down of the US "war on terror" detention center by end of 2007 because the actual number of dangerous detainees was low.

"We have looked at all the categories of detainees: those who are supposed to be transferred, those who are valuable for procedure," Lizi told reporters.

"The number of those, when you discuss it with the people in this jail, could move from 70 to a little more than 100 but not more. And in some cases, people say we could have only 30 to 40 real valuable cases," she said.

Her report says Guantanamo now has some 460 detainees.

The Supreme Court issued a landmark ruling Thursday against the US use of military tribunals for Guantanamo Bay detainees, but the verdict did not touch the detention center's future.

The ruling has forced the US administration to rethink its strategy for the "war on terror" tribunals.
