A group of 10 to 12 people said to be linked to PKK terrorist group attacked the Turkish Embassy and consulate general buildings with paint in Brussels on Sunday.
Diplomatic sources said the assailants threw red paint on the front area of the buildings.
Police officers arrived after the attack to investigate the incident.
The buildings were later cleaned up following the incident.
Attacks on Turkish buildings in Europe have intensified after Turkey launched Operation Olive Branch on Jan. 20 to remove the PYD/PKK and Daesh terrorists from Afrin, northwestern Syria.
The operation is being carried out under the framework of Turkey's rights based on international law, UN Security Council resolutions, its self-defense rights under the UN charter, and respect for Syria's territorial integrity, it said.
The military also said only terror targets are being destroyed and "utmost care" is being taken to not harm civilians.
