Yemen hostage: US reveals bid to rescue Luke Somers

The US has revealed it tried to rescue UK-born American hostage Luke Somers, who is being held by al-Qaeda in Yemen.

President Barack Obama authorised the mission last month, it said.

"Regrettably, Luke was not present, though hostages of other nationalities were present and were rescued," the National Security Council said.
