Turkey summons United States Ambassador John R. Bass to protest alleged "aggressive and unprofessional actions" by American security personnel against Turkish bodyguards, calling for the United States to conduct a full investigation on the May 17 clashes. The American ambassador told Turkey's government that its guards violated U.S. laws. Last week, the U.S. summoned Turkish Ambassador Serdar Kılıç to discuss about Turkish security officers hitting and kicking peaceful protesters outside the Turkish ambassador's residence in Washington, D.C.
