Turkey summoned the U.S ambassador to Ankara to protest what it called "aggressive and unprofessional actions" by American security personnel against Turkish bodyguards in Washington during President Recep Tayyip Erdoğan's visit last week.
US officials said Erdoğan's bodyguards attacked a small group of pro-Kurdish protesters gathered outside the building and the incident ignited a storm of controversy. A video shared on social media showed Erdoğan watching the melee.
The ministry summoned John Bass, the American ambassador in Ankara, to deliver a written and verbal protest.
The ministry accused US security personnel of acting "contrary to diplomatic rules and practices... towards the close protection team" of Turkish Foreign Minister Mevlüt Çavusoğlu in front of the Turkish embassy chancery in Washington.
The ministry said it told Bass there were "lapses of security" during Erdogan's stay.
It hit out at "the inability of US authorities to take sufficient precautions at every stage of the official programme."
Two Turkish bodyguards were briefly detained after the incident but later set free and returned to Turkey. The United States summoned the Turkish ambassador to raise concerns over the altercation.
