A picture released by the Armenian Genocide Museum-Institute purportedly shows Armenians hung by Ottoman forces in Constantinople in June 1915. Armenians say up to 1.5 million of their forebears were killed in a 1915-16 genocide by Turkey’s former Ottoman Empire. Turkey says 500,000 died and ascribes the toll to fighting and starvation during World War I. AFP PHOTO / ARMENIAN GENOCIDE MUSEUM INSTITUTE
