Two Tunisians who had been detained at Guantanamo arrived in Italy late Monday and will be tried on international terrorism charges for having allegedly recruited fighters for Afghanistan, officials said.

Adel Ben Mabrouk, 39, and Mohamed Ben Riadh Nasri, 43, are suspected of being members of a terror group with ties to al-Qaida. They were immediately taken into custody upon arrival in Milan and were being interrogated, a prosecutor told The Associated Press.

A third Guantanamo detainee was being relocated to France, and a fourth to Hungary, according to a U.S. official who spoke on condition of anonymity because the person was not authorized to discuss the release.

Guantanamo prisoner Saber Lahmar arrived in Bordeaux, France, early Tuesday, his Boston-based lawyer Robert Kirsch confirmed.

"We are grateful for the courage and generosity of the French people and government," Kirsch said, adding that Lahmar will now have "a chance to rebuild his life in France."

Lahmar is one of six Algerians who were detained in Bosnia in 2001 on suspicion of plotting to bomb the U.S. Embassy in Sarajevo, but a judge later cleared five of them, including Lahmar, for lack of evidence.

The identity of the detainee being transferred to Hungary was not immediately available. The Washington Post said he was a Palestinian.

In September, two Uzbeks were sent to Ireland, and recently two Syrians arrived in Portugal. But they were freed. In the case of the Tunisians, Italian magistrates had previously accused them of international terrorism stemming from crimes allegedly committed as far back as 1997 and they arrived in Italy already in detention.

Italy took in the Tunisians as a "concrete political sign" of Italy's commitment to help the U.S. close Guantanamo, Justice Minister Angelino Alfano said in a statement.

The Italian prosecutor, who spoke on condition of anonymity, said Mabrouk and Nasri traveled from Italy to Afghanistan and, once there, maintained a "functional relationship inside the organization" of Tunisians here to recruit fighters for suicide missions.

Nasri was allegedly the head of the organization and was described by the U.S. military as a "dangerous" Tunisian operative when he appeared before a U.S. military review panel.

President Barack Obama confirmed last month that he would miss his January deadline to close the Guantanamo prison _ partly because he cannot persuade other nations to take the detainees.
