A suicide bomb attack at a busy shopping area in the Turkish city of Istanbul has killed at least four people, officials say. Another 36 were injured – 12 foreign nationals – as the bomb went off near a government building on Istiklal Street.
No-one has admitted carrying out the attack, the latest to target Turkey in recent months. The Turkish government has blamed Kurdish militants for previous attacks and has retaliated against them. Three Israeli tourists were among those injured, local media report say. The Israeli foreign ministry has confirmed Israelis were wounded, but has not given the number or said what condition they are in.
Both the so-called Islamic State (IS) and Kurdish militants have claimed 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.
