The White House says a new video purporting to show an Islamic State group fighter beheading a British hostage is another demonstration of the extremist group’s brutality.
Lisa Monaco is President Barack Obama’s counterterrorism adviser. She says the U.S. has seen the video released Friday and is evaluating it.
Monaco says the hearts of those at the White House go out to the aid worker believed to be in the video and to other hostages being held and their families.
She says the apparent beheading is another clear example of why Obama is moving to degrade and destroy the Islamic State group.
If authentic, the video would represent the fourth such killing by the group now targeted in U.S.-led airstrikes. It ends with an Islamic State fighter threatening an American.
