President Obama on Wednesday condemned the execution of journalist James Foley at the hands of ISIS, saying the militant group had "no place in the 21st century."
"No just God would stand for what they did yesterday and what they do every single day," he said.
On Tuesday, ISIS released a video of an executioner beheading Foley, who was kidnapped two years ago in Syria. The White House on Wednesday confirmed the authenticity of the video.
In a stern statement, Obama also said that he would not halt airstrikes against ISIS despite the group's threat that it would kill more civilians unless the U.S. backed down.
