According to Turkish President Recep Tayyip Erdogan, Kurdish militants are to be held squarely responsible for the blast at a bus stop in downtown Istanbul.

Erdogan went on to say that PKK militants often stage terror attacks in large cities, thus trying to help the Kurds gain their independence.

Recep Tayyip Erdogan said that his country will fight terrorism to the bitter end.
