Thousands of migrants who gathered on the Turkey-Greece border clashed with Greek police. They responded by firing tear gas at people who amassed at a border crossing in the western Turkish province of Edirne, some of whom responded by hurling stones at the officers. Turkey's president Recep Tayyip Erdogan promised to let refugees to travel on to Europe from Turkey. "What did we do yesterday? We opened the doors," Turkish President Erdogan stated.
