Turkey on Monday summoned the US ambassador in Ankara to protest about the "aggressive" action taken against President Recep Tayyip Erdogan's bodyguards after they got into a brawl with protesters in Washington.

The action appeared to be in retaliation to calls in the US for strong measures against the Turkish security officers who were seen attacking protesters outside the Turkish ambassador's residence during Mr Erdo?an's visit last week.

Two members of the security team were detained briefly before being released, but calls are growing for a more forceful US response to violence on American soil.

John McCain, the Republican senator, has said the government should "throw their ambassador the hell out" of the US.
