Washington, January 11 (RHC)-- The Barack Obama administration has launched an internal investigation of a drone strike that reportedly killed 12 people in Yemen last month. The victims were on their way to a wedding when they were apparently mistaken for an al-Qaeda convoy.

NBC News reports the strike was carried out by the Joint Special Operations Command, or JSOC. The White House probe comes after the human rights group Reprieve released new video showing the victims’ burned corpses lined up on the ground for burial.

In a statement, Reprieve said: "In bombing a wedding, the U.S. government has demonstrated that they either don’t know or don’t care who they were targeting. As a result, 12 innocent lives have been lost and many more destroyed... We can only hope [the] internal investigation is robust and that it results in needed policy change and reparation for those affected."
