Erdogan addressed hundreds of thousands of pro-Palestine supporters at a rally in Istanbul, delcaring Israel as a "war criminal" that may be met with military force if it continues its assault on Gaza."The main culprit behind the massacre unfolding in Gaza is the West. Israel has been openly committing war crimes for 22 days, but the Western leaders cannot even call on Israel for a ceasefire, let alone react to it," Erdogan told the crowd, who were waving Palestinian flags. "With this attitude, the West has accumulated a lot of sins."
