Turkish President Recep Tayyip Erdoğan on Saturday called out Western powers as "the main culprit" behind Israel's "massacre" of Palestinians in Gaza. The call came during the "Great Palestine Meeting" held in Istanbul, which was joined by over 1.5 million people, according to the organizers. President Erdoğan, who has been a leading international supporter of Palestinian rights, unleashed a scathing attack at Israel and its Western supporters. "The main culprit behind the massacre unfolding in Gaza is the West," he told the Turkish and Palestinian flag-waving crowd.
