ISTANBUL: Turkey's president has criticized NATO for not supporting the country's ongoing military operation against Syrian Kurdish fighters in Syria. Speaking to supporters Saturday, Turkish President Recep Tayyip Erdogan asked, "Hey NATO, where are you?" and accused the alliance of double standards. Erdogan said Turkey sent troops to conflict zones when requested, but did not receive support in return. Turkey launched a solo military offensive against the Syrian Kurdish People's Protection Units or YPG on Jan. 20 to clear them from Afrin in northwestern Syria. The country considers the YPG a terror organization but its NATO ally, the United States, backs the fighters to combat Daesh. Erdogan urged NATO to come to the aid of Turkey, saying its borders are "under threat right now." - Agencies
