Ten Yemeni men held at the Guantanamo Bay US military prison have been sent to Oman bringing the detainee population below the symbolically important milestone of 100, as President Barack Obama steps up efforts to close the facility before he leaves office.
Their Thursday transfer to the Gulf Arab state marked the largest group of prisoners shipped out of the detention centre at the US naval base at Guantanamo Bay, Cuba, since Obama began his presidency in 2009 pledging to quickly shutter a prison that has drawn international condemnation.
The Yemenis, all held for more than a decade without charge or trial, were part of a wave of releases that the Obama administration signalled would take place early this year as it prepares to give Congress a plan for closing the facility.
Four other detainees were moved out already this month.
Obama, whose term in office ends in January 2017, has vowed to push ahead with his efforts but faces opposition in the Republican-led Congress.
Lawmakers have created obstacles to moving any Guantanamo prisoners to facilities in the United States.
In Muscat an Omani official was cited by the state news agency as saying the Yemenis had arrived and would remain there for humanitarian reasons until conditions in Yemen, gripped by civil war, allow them to be sent home.
Oman, a close US ally, had accepted earlier groups of Guantanamo prisoners.
US Defense Secretary Ash Carter said the transfer followed a "deliberate and careful review".
"We completed the transfer of 10 Yemenis - roughly 10 per cent, that is, of the total remaining Gitmo population - to the government of Oman," Carter told an audience at the US military's Southern Command, which oversees the military detention facility.
The 93 prisoners remaining at Guantanamo mark the lowest number since 2002, shortly after then-President George W Bush opened the facility to house foreign terrorism detainees after the September 11, 2001, attacks on the United States.
