Turks living in Belgium hold protest on the events of 1915, entitled "Listen to me", Anadolu reported on Saturday.
The action involved more than 3,000 people, who are calling on Armenia to open archives to investigate the events.
Armenia and the Armenian lobby claim that Turkey's predecessor, the Ottoman Empire allegedly carried out "genocide" against the Armenians living in Anatolia in 1915. Turkey in turn has always denied "the genocide" took place. While strengthening the efforts to promote the "genocide" in the world, Armenians have achieved its recognition by the parliaments of some countries.
