Turkish authorities on Monday detained 15 members of an anti-American youth organization who assaulted two U.S. military personnel in the city of Izmir, the state-run Anadolu news agency reported.

The agency said members of the Turkish Youth Union, which is affiliated with the Patriotic Party — a small, nationalist political party without parliament seats — were arrested on the orders of a prosecutor.

The group posted a video of the incident on X and said it placed sacks over the heads of soldiers who had disembarked from the U.S. Navy amphibious assault ship Wasp.

The video shows a group of men yelling, "Yankee go home!" while restraining a man and attempting to put a sack over his head.

"The U.S. soldiers who carry the blood of our soldiers and thousands of Palestinians on their hands cannot pollute our country," the group said on X.

The U.S. Embassy confirmed the incident, saying service members on board the USS Wasp were "now safe." It thanked Turkish authorities for their "rapid response and ongoing investigation."

The USS Wasp arrived in Izmir on Sunday after conducting joint training with Turkish assault ships in the Mediterranean.
