The federal prosecutor’s office said on Friday that two former Guantanamo prison inmates have been detained by Belgium allegedly for seeking to provide recruits to fight in Syria with opponent groups.
The two men, who were under police surveillance, were arrested early on Thursday in Antwerp city in Belgium along with three others.
"They were in a car, we believe waiting to commit a robbery," a spokesman for Belgium's federal prosecutor, Jean-Pascal Thoreau said.
Moussa Zemmouri (37), a Belgian of Moroccan origin, was captured in Kandahar, Afghanistan after the Sept. 11, 2001 attacks.
Zemmouri was sent back to Belgium in 2005 and spent some time in a prison there before being released.
The other suspect, identified as Soufiane A, an Algerian, is claimed to have spent some time in Syria.
Guantanamo prison was established after Sept. 11 attacks in Cuba and used mainly for Al Qaeda and Taliban detainees.
US President Barack Obama had promised upon coming to office to close down the Guantanamo prison camp and has significantly reduced the number of inmates by transferring them to third world countries.
