A suicide bomb attack at a busy shopping area in the Turkish city of Istanbul has killed at least four people, officials say.
Up to 20 people were injured, three seriously.
The area - Istiklal Street - is reportedly crowded at weekends.
The attack in Istanbul - Turkey's largest city - occurred around 11:00 (09:00 GMT).
Three Israeli tourists were among those injured, local media report say. The Israeli foreign ministry has confirmed Israelis were wounded, but not given the number or said what condition they are in.
Both the so-called Islamic State (IS) and Kurdish militants have claims recent attacks in Turkey.
President Recep Tayyip Erdogan has said terror groups are targeting civilians because they are losing their struggle against Turkish security forces.
Turkey is part of the US-led coalition against IS and allows coalition planes to use its air base at Incirlik for raids on Iraq and Syria.
