ISTANBUL Turkish President Recep Tayyip Erdogan on Saturday reaffirmed Ankara's commitment to rooting out terror groups in neighboring Syria, while outlining a vision of regional unity, peace, and self-determination. "We have zero tolerance for the YPG terrorist organization, which occupies one-third of the country (Syria). We will soon take steps to resolve this issue once and for all," Erdogan said at a provincial event of his Justice and Development (AK) Party in the southern city of Mersin.
