A man wearing a Hamas headband held up a bloody face mask depicting President Biden on Saturday amid an anti-Israel protest outside the White House. 

The man and others wearing similar headbands shouted "Down, down occupation!" while another man lit an American flag on fire and others flew Palestinian flags.

Other agitators at the demonstration threw objects at a National Park Service ranger, shouting "piggy, piggy!" at him, and defaced statues in Washington, D.C.

Holding signs that accused Biden of being on "the wrong side of history," protesters converged on the White House Saturday morning after security measures at 1600 Pennsylvania Avenue were tightened in anticipation of the planned demonstration.

Protesters waved Palestinian flags, chanted "Free Palestine!" and held signs, urging Biden to stop his support for Israel. 

Although the protest started out peacefully, hostile demonstrators soon began targeting park rangers, shouting "F-you, fascist!" and "piggy, piggy, oink, oink!" 

More peaceful demonstrators began making a human chain around the White House, which they referred to as "the people's red line," a reference to Biden saying Israel has not crossed his "red line" in the war.

"May the cries of all the kids you bomb haunt you," another protester's sign read.

Biden has been in France since Wednesday, when he arrived in the country for D-Day anniversary ceremonies and a state visit with French President Emmanuel Macron on Saturday. A White House spokesman said the president respects the right to protest, but believes endorsement of terrorism is "repugnant."

"President Biden has always been clear that every American has the right to peacefully express their views," said spokesman Andrew Bates. "But he has also always been clear that Antisemitism, violent rhetoric, and endorsing murderous terrorist organizations like Hamas is repugnant, dangerous, and against everything we stand for as a country."
