Portuguese authorities are evaluating security in case the country receives two or three prisoners from the U.S. detention camp at Guantanamo Bay in southern Cuba, Foreign Minister Luis Amado said on Friday. 'Many situations are being analyzed,' Amado said, adding that implications related to security must be considered. Portugal is the first Europe Union member to offer asylum to some of the 229 'war or terror suspects' detained at Guantanamo Bay, an American naval base in southern Cuba. Spain, France, Ireland, Britain and Italy later followed suit. Amado met with American special envoy Daniel Fried on June 19 in Lisbon to discuss the closing of Guantanamo. The United States has sent Portugal the reports of some prisoners who are likely to be taken by the country. The Guantanamo prison, opened after the Sept. 11, 2001 attacks on the United States, has drawn international criticism for holding prisoners indefinitely, many without charge.
