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.
