Video emerges of Erdogan watching mass brawl between his guards and protesters in Washington

New footage has emerged showing Turkish President Recep Tayyip Erdogan looking on as his armed guards violently clash with a group of protesters outside the Turkish ambassador's residence in Washington D.C. on Tuesday.

The violence appears to have broken out after Erdogan gave a signal to his security team. The video shows one of the president's aides communicating with Erdogan, who is sat in the back of a black Mercedes sedan, before walking towards the demonstrators.

Seconds later, other members of the presidential security detail run towards the protesters to confront them. One of the aides returns to the car as Erdogan leaves the vehicle. He appears to briefly watch his guards violently break up the protest before entering the Turkish ambassador's residence.

Nine people were hospitalised after the clash and two were arrested. Ayten Necmi, 49, was charged with aggravated assault and Jalal Kheirabaoi, 42, was charged with assaulting a police officer.

The confrontation came after President Donald Trump welcomed Erdogan to the White House on 16 May. Praising the Turkish president as a strong ally in the fight against terrorism, Trump chose not to address Erdogan's authoritarian crackdown on his own people.

The US State Department condemned the violence and summoned Turkish ambassador Serdar Kilic to a meeting on 17 May. The details of the conversation were not disclosed.

Republican Senator John McCain told MSNBC's 'Morning Joe' on Thursday that the US should throw "the ambassador the hell out of the United States."

"This kind of thing cannot go unresponded to diplomatically," he said. "And maybe in other ways. Maybe bring lawsuits against so we can identify these people."

The White House did not comment on the incident.
