Arsonists targeted two vehicles owned by Turkish nationals, one of them a diplomat, in the northern Greek city of Thessaloniki, destroying the cars and damaging another four, Greek authorities said Monday.
Police said the arsonists struck in the pre-dawn hours of Monday, pouring flammable liquid over the two cars before torching them.
One is owned by a diplomat working at the Turkish consulate, the other by a Turkish national employed at an international financial institution headquartered in Thessaloniki.
Another four private cars parked nearby were severely damaged in the attack.
There was no immediate claim of responsibility.
The incident comes amid tension between Ankara and Athens over sovereign rights and international law in the Aegean and Eastern Mediterranean.
