Q: Investigators were paying particular attention to two members of the Turkish security detail who assaulted American Diplomatic Security officers assigned to protect the visiting delegation. 
  
 The men were briefly detained on the scene Tuesday and their guns confiscated. But when it was determined that they held diplomatic status, they were promptly released, according to a congressional aide briefed on the State Department’s investigation. By the time video of what had happened outside the ambassador’s residence shot across the internet Tuesday night, stoking outrage in the United States, the two men were on their way out of the country with Mr. Erdogan and the rest of his entourage. 
  
 The two men remain the subject of an active criminal investigation and will not be allowed to re-enter the United States, the aide said. 
  
 The congressional aide and others who shared details about the case spoke on the condition of anonymity to discuss details of the investigation. They declined to identify the two members of the Turkish security forces who were detained, but said their immunity was no longer in place. 
  
 The Turkish Embassy in Washington and officials in Turkey did not respond to requests for comment on Thursday. The embassy issued a statement on Wednesday contradicting much of the American officials account and laying blame for the episode on protesters who they said had incited the violence. 
  
 The exchange between Turkish security personnel and American diplomatic officers sheds light on just how far the Turks strayed outside the bounds of typical diplomatic behavior on Tuesday. It also highlights the challenge facing American officials who must navigate potential diplomatic immunity claims, not to mention political repercussions, even as they pledge to hold those involved accountable. ||||| These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to.

 The clash happened Tuesday in Washington, D.C., near the home of Turkey’s ambassador. Erdogan had met with President Donald Trump at the White House earlier in the day. 
  
 Parts of the clash were caught on video by VOA’s Turkish Service. 
  
 ​State Department official Heather Nauert said in a statement the U.S. concerns would be communicated to the Turkish government "in the strongest possible” way. 
  
 “Violence is never an appropriate response to free speech, and we support the rights of people everywhere to free expression and peaceful protest,” the statement said. 
  
 VOA’s Turkish Service said the protesters were supporters of Selahattin Demirtas, a jailed pro-Kurdish lawmaker. Turkish officials arrested him in November on terrorism-related charges. 
  
 Rights groups condemned his arrest as part of a government crackdown on dissent. 
  
 The protesters said they were demonstrating peacefully until Erdogan’s guards and supporters suddenly moved toward them. Video shows men wearing dark suits and others hitting and kicking protesters. Police appeared to struggle to keep the two groups separated. 
  
 At least 11 people were injured in the violence. 
  
 Two arrests were made and Washington, D.C. police said other suspects were being sought. Police said they were checking reports that some of the attackers worked as bodyguards for the Turkish president. 
  
 Turkey’s embassy blamed the violence on groups linked to the Kurdistan Workers’ Party (PKK) – a group fighting the government. An embassy statement said the group had “aggressively provoked Turkish-American citizens” who had gathered to greet Erdogan. 
  
 Washington’s police chief, mayor and several U.S. lawmakers condemned the violence. Senator John McCain, a Republican, urged the Trump administration to expel the Turkish ambassador over the incident.

A:
A DC protest that turned violent earlier this week made headlines because armed members of the visiting Turkish president's security detail were seen pummeling protesters near the home of Turkey's ambassador. Nine people were hospitalized, and the violence stirred outrage online as critics of Recep Tayyip Erdogan accused him of bringing his oppressive tactics against dissent to the US. A new video won't help. It shows Erdogan surveying the violent scene with aides upon exiting a car, reports the New York Times. Perhaps worse is a chain of events laid out on Twitter by Washington Post reporter Philip Bump. As Bump puts it, it "looks like Erdogan telling his goons to assault peaceful protesters in America." Before Erdogan emerges from the car, an aide ducks his head in, then pops out and speaks to another man, who heads toward the protesters. Within seconds, the violence breaks out. Bump writes that the video of Erdogan could "raise the stakes" in the controversy. The White House has been silent on the protest and violence, though a State Department spokesperson said that "violence is never an appropriate response to free speech," and that those concerns would be relayed to Turkey's government "in the strongest possible way," per the Voice of America. Turkey, for its part, denies any role in inciting violence. Two members of Erdogan's security detail who clashed with American security personnel were detained, then released because of diplomatic protection. They will not be allowed to return to the US, a congressional aide tells the Times.
