American beheaded by ISIS

American beheaded by ISIS

ISIS terrorists beheaded an American over the weekend.

That brings the total to five westerners the militants have murdered.

The group is now threatening U.S. soldiers, as the Pentagon steps up plans to defeat these terrorists.

The fifteen-minute video purportedly shows ISIS militants, their faces exposed, decapitating Syrian soldiers.

At the end a masked man with a British accent stands over the severed head of American aid worker Peter Kassig, a U.S. soldier turned aid worker kidnapped in Syria last year.

He is the 3rd American, and the 5th western hostage killed by ISIS.

Unlike previous ISIS videos, it doesn't show Kassig alive before the beheading. But the group does identify their location as Dabiq, a town in northern Syria, and threatens U.S. military personnel.

"Tomorrow we'll be slaughtering your soldiers," said one man in the video.

Residents of Kassig's home state of Indiana remember the sacrifices he made to help Syrians in need.

"He risked his life every day to save the lives of people that he didn't have any relation to and we will forever be grateful for that," said one woman.

On Sunday, the White House confirmed the video is authentic and President Obama called the murder an act of pure evil. The U.S. is pressing forward with its effort to ultimately destroy the terror group.

Defense Secretary Chuck Hagel said Sunday the U.S. military is speeding up its training and advising of Iraqi forces who are fighting ISIS.

"We're in the process now of opening four training centers in Iraq," said Hagel.

Hagel says Americans should prepare for a long and difficult struggle.

Kassig's parents say they're heartbroken by their son's killing, but incredibly proud of his humanitarian work.
