WASHINGTON, December 5 (Sputnik) – The White House has announced that the details of a US operation, aimed at rescuing hostages held by al-Qaeda in Yemen, including US citizen Luke Somers, are classified and will not be disclosed.
Earnest added that the US mission "was coordinated with the Yemeni government and was undertaken by US and Yemeni forces".
"Their effort should serve as another signal — a clear signal — to those who would do us harm that the United States will spare no effort to secure the safe return of our citizens and to hold their captors accountable," Earnest stressed.
On Wednesday night, kidnappers threatened to kill Somers, if the US government did not respond to their demands in three days' time. The US citizen was reportedly working in Yemen as a freelance journalist before he was captured by al-Qaeda in the capital Sanaa.
In August, the Obama administration made public that it had sent special operations troops into Syria to rescue US hostages, including American journalist James Foley. The operation was unsuccessful. Later Foley was executed by Islamic State (IS) militants.
According to the US Bureau of Counterterrorism, 12 Americans have been kidnapped by terrorist organizations in Syria, Libya, Yemen, Nigeria and Colombia.
