Story highlights In a Facebook post, Rep. Clay Higgins calls for the killing of any person suspected of having terror links

He also labeled the world as fighting a holy war, saying "all of Christendom... is at war with Islamic horror"

Washington (CNN) A Louisiana congressman responded to the terror attack in London by calling for an extreme solution: Kill anyone suspected of being an Islamic radical.

Rep. Clay Higgins, a first-term congressman representing the third congressional district of Louisiana, wrote a Facebook post Sunday just hours after a terror attack in London that killed at least seven people

"Not one penny of American treasure should be granted to any nation who harbors these heathen animals. Not a single radicalized Islamic suspect should be granted any measure of quarter. Their intended entry to the American homeland should be summarily denied. Every conceivable measure should be engaged to hunt them down. Hunt them, identity them, and kill them. Kill them all. For the sake of all that is good and righteous. Kill them all."

He also labeled the world as fighting a holy war, saying "all of Christendom... is at war with Islamic horror."

When asked for further clarity on the post, Higgins' office confirmed that the post, while posted on a campaign page and not official congressional office account, was authentic and from Higgins.
