Suspected Istanbul bomber's father arrested

Turkish authorities arrest the father of the suspected Istanbul bomber Savas Yildiz.

Yildiz is believed to be the suicide terrorist who detonated himself on an Istanbul pedestrian boardwalk Saturday, killing three Israelis, an Iranian and at least one more person, and wounding as many as 36 others.

Turkish media say Yildiz’s father provided authorities with a blood sample to compare to blood collected from the scene of the explosion, which will be used to confirm Yildiz’s presence at the scene of the attack.

Yildiz was responsible for at least two previous terror attacks on Turkish soil, authorities say, including an attack in Adana last year. He is believed to have fled to Syria to join the ranks of Islamic State after that attack, and may have returned to Turkey at IS’s behest to carry out Saturday’s bombing.
