A Louisiana Republican called for a religious war against Islamic terrorists in the wake of attacks over the weekend in London.

Freshman Rep. Clay Higgins (R-LA) called for violent action against suspected terrorists in a Facebook post, alongside a photo of police taking a suspect into custody after an attack Saturday at London Bridge killed seven people and injured nearly 50 others.

“The free world— all of Christendom— is at war with Islamic horror,” Higgins wrote.

“Not one penny of American treasure should be granted to any nation who harbors these heathen animals,” the lawmaker continued. “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,” he added. “Hunt them, identity them, and kill them. Kill them all. For the sake of all that is good and righteous. Kill them all.”

Higgins is a former police captain in Louisiana before his election to Congress in November.
