Protesters clashed with police at a demonstration in Athens held in protest over the recent agreement between Greece and the Former Yugoslav Republic of Macedonia (FYROM) to settle their ongoing naming dispute.
Similar protests have turned violent in the past.
Under the deal — which will take months to be finalized — Macedonia will be renamed "North Macedonia.
The agreement still needs to be ratified by the Macedonian parliament however, and then confirmed via referendum in September.
It would end a 27-year dispute that started after Greece objected to its northern neighbor's name, saying it implied claims on the adjacent Greek province of Macedonia.
Hardliners on both sides of the border oppose the agreement, saying it offers too big concessions to the other country.
