Guantanamo Bay: US in largest detainee transfer under Obama

The US says it has sent 15 Guantanamo Bay detainees to the United Arab Emirates - the largest single transfer during President Barack Obama's administration.

The Pentagon says the transfer of 12 Yemeni nationals and three Afghans brings the total number of prisoners down to 61 at the US facility in Cuba.

The released inmates had been held without charge, some for over 14 years.
