WASHINGTON (Sputnik) — Last week, US media reported that Ahmed Mustafa Dhiab, a Syrian national released from the US detention facility at Guantanamo Bay to Uruguay in 2014, disappeared across the border to Brazil.
"I can’t confirm that," Cook said in response to the reports of the missing detainee.
The Defense Department has seen the reports of the missing prisoner and is "tracking" the development, Cook said, adding that Dhiab’s questionable whereabouts are "something, obviously, we take very seriously."
In 2014, Uruguay took five detainees from Guantanamo Bay, becoming the first South American country to accept such individuals transferred as part of President Barack Obama’s effort to close the detention facility.
