Nineteen people, including 15 members of Turkish President Recep Tayyip Erdogan’s security detail, have been indicted for attacking protesters during Erdogan’s visit to Washington, D.C., in May.

The charges, dealt by a grand jury in D.C., detail the incident in which the defendants attacked the peaceful demonstrators outside of the Turkish embassy. All 19 are charged with conspiracy to commit a crime of violence, a felony punishable by a statutory maximum of 15 years in prison, according to the Associated Press. Several face additional charges of assault with a deadly weapon.
