A decision by United States authorities to arrest Turkish security guards involved in a brawl in Washington in May is a scandal, President Recep Tayyip Erdogan said on Friday, according to The Independent.
"This is a complete scandal. It is a scandalous sign of how justice works in the United States".
On Tuesday, a grand jury indicted 19 people, including 15 Turkish security officials, over the brawl between protesters and Erdogan's security personnel in May.
The May 16 skirmish injured 11 people outside the Turkish ambassador's residence and further strained bilateral ties at a time when the North Atlantic Treaty Organisation allies are in sharp disagreement over policy in Syria.
Ankara also blamed the violence on pro-Kurdish demonstrators linked to the homegrown Kurdistan Workers' Party (PKK), which both the USA and Turkey view as a terrorist organization.
Erdogan said the United States had failed to provide him protection from members of the PKK during his visit, and added he would discuss the issue with President Donald Trump in his next visit.

Ankara also slammed the decision of the United States authorities to allow pro-PKK protesters to rally close to the Turkish ambassador's residence since Ankara and Washington both recognise the PKK as a terrorist organisation.
The Turkish president said that the U.S. is now hiding Fethullah Gulen, whose involvement in the military coup attempt in Turkey has been proved.
