A Turkish mob, most of whom had been trucked into the city in advance, assaulted Istanbul's Greek community for nine hours. Although the mob did not explicitly call for Greeks to be killed, over a dozen people died during or after the attacks as a result of beatings and arson. Armenians and Jews were also harmed. The police remained mostly ineffective, and the violence continued until the government declared martial law in İstanbul and called in the army to put down the riots.
