When the US government asked years ago that countries take in detainees freed from the Guantanamo military prison, only tiny Albania answered the call. The rest of Europe had long criticized the US military detention center in Cuba and the Bush administration for opening it in January 2002 to hold so-called "enemy combatants" accused of having links to the al-Qaida terror network or Afghanistan's ousted Taliban regime. Now Europe appears to be open to helping, as President-elect Barack Obama has pledged to close the prison. Most Europeans held in Guantanamo have been returned to their home countries, but US Defense Secretary Robert Gates has called for proposals for transferring the remaining 250 or so detainees - amid concerns that some could be persecuted if sent back to their home nations. Most come from Yemen, but others are from Azerbaijan, Algeria, Afghanistan, Chad, China and Saudi Arabia. Some have been held without charge since the prison camp opened. Portugal, France, Germany and Switzerland said they would consider taking in some of the remaining detainees. "We've encouraged other nations to accept detainees from Guantanamo, and we're pleased with the recent discussions," Pentagon spokesman Navy Cmdr. Jeffrey Gordon said Tuesday, adding that US authorities wanted to make sure the detainees - if released - would not be mistreated or pose a threat to the international community. The US military had said it would prosecute about 70 prisoners in military tribunals, but fewer than 20 have been charged. It is unclear what would happen to them should the detention camp be shut and the trials halted. The Bush administration holds that the Guantanamo facility should be closed, but it has fought doggedly to keep all remaining inmates outside the United States, arguing that they are too dangerous to bring into the country. Most speculation about the possibility of housing the prisoners within the US has centered on the military prison at Fort Leavenworth, Kansas. But officials there have said the facility is not secure enough, and Kansas senators Sam Brownback and Pat Roberts six months ago protested in a letter to the Bush administration that Leavenworth's only secure wing was too small. A French diplomat said Tuesday that France was considering hosting Guantanamo detainees, but said a Europe-wide discussion was needed. The diplomat spoke on condition of anonymity in line with government policy. A lawyer who defended ex-Guantanamo inmates in French courts, William Bourdon, said the French government was in discussions to take in Guantanamo prisoners. "There is an obligation of solidarity with these people who were held for so long without legal recourse," Bourdon said, without elaborating. German Foreign Minister Frank Walter Steinmeier has asked officials to look into the legal, political and practical aspects of accepting detainees, as "he does not want to see the plan to close Guantanamo fail due to the need to find somewhere for those prisoners," according to ministry spokesman Jens Ploetner on Monday. German Chancellor Angela Merkel has long called for the camp's closure, but her spokesman Thomas Steg said Germany would not accept prisoners if conditions were attached. Portugal is willing to grant asylum to Guantanamo detainees who cannot return home, according to a letter sent by Portuguese Foreign Minister Luis Amado to his European Union counterparts this month. Amado wrote that the EU "should send a clear signal of our willingness to help the U.S. government resolve this problem, namely by taking in the detainees." He is expected to raise the issue at a January meeting of the bloc in the Czech capital, Prague. Switzerland also is "ready to seriously examine" a U.S. request, Swiss government minister Moritz Leuenberger said. EU nations are more inclined to help resolve the Guantanamo situation now that President George W. Bush is leaving office, an official from the bloc said Tuesday on condition of anonymity because he was not authorized to speak to reporters. The Europeans' willingness to help marks a sharp turn from their reluctance in 2006, when only the Balkan nation of Albania offered to accept five Turkic-speaking Muslims called Uighurs from China's far western province of Xinjiang, where Chinese authorities accuse them of waging a separatist campaign. The Uighur detainees said they were fighting against Chinese occupation. More than a dozen Uighurs remain in Guantanamo, though, and Albania has said nothing about the possibility of taking them in. US authorities have refused to return them to China for fear they may face persecution.
