Four dead after suicide bomb attack in central Istanbul

The Istanbul derby between Galatasaray and Fenerbahce has been postponed because of "security concerns" in Turkey's biggest city.

Istanbul local authorities and the Turkish Football Federation determined the match, due to be played on Sunday evening, would be put back to a later date.

The decision came in the wake of a suicide bomb attack in Istanbul on Saturday which killed five people and left dozens injured.

Galatasaray announced the postponement, with a statement on Twitter saying: "Due to security concerns based on information provided by the TFF, Istanbul council and police force, tonight's match has been postponed."

So-called Islamic State were behind Saturday's suicide bomb that killed five people and wounded 36 in Istanbul, says the Turkish Interior Minister.

The bomber, who died in the attack, has been named as Mehmet Ozturk, born in 1992 in Gaziantep, a province in south-central Turkey.

"We have determined that Mehmet Ozturk, born in 1992 in Gaziantep, has carried out the heinous attack on Saturday in Istanbul. It has been established that he is a member of Daesh," Turkey's Interior Minister, Efken Ala told reporters.

Five other people have been detained over Saturday's suicide bombing, officials said.

Israel has confirmed that three of its citizens died in the blast. Two of them held dual citizenship with the United States. An Iranian was also killed, Turkish officials have said.

Two Americans were killed in the suicide bomb attack in Istanbul, the White House said in a statement.

Five were killed in the attack - including the bomber - and 36 were injured.

Turkish Prime Minister Ahmet Davutoglu denounced the suicide bombing that killed five people and wounded 36 in Istanbul on Saturday as "inhumane".

He said Turkey would continue its struggle against "centres of terrorism".

At least one Iranian and two Israelis are among the dead from the suicide bombing in Istanbul.

Five were killed in the attack - including the suicide bomber - and 36 were injured - including a number of Irish citizens.

The attack took place on Istiklal Street, home to upscale shops and foreign consulates.

A "number" of Irish citizens have been injured in a suicide bomb attack in central Istanbul, the country's minister for trade and foreign affairs Charlie Flanagan has confirmed.

Israeli citizens were also among the 36 people injured in the blast, which killed four bystanders.

A suicide bomber who killed four people and injured 36 others in an attack in Istanbul may have been from the so-called Islamic State militant group, Turkish officials have said.

Officials earlier said they believed the banned Kurdish Workers Party (PKK) was behind the attack, but now say new evidence suggests it have been the work of either the PKK or Islamic State.

No group has yet claimed responsibility for the attack.

Armed police have put central Istanbul on lockdown after the explosion in Istiklal Street, a pedestrian boulevard lined with international shops, cafés, theatres and foreign consulates.

Four bystanders, plus the bomber, were killed in the blast while 36 others were hurt. Turkey's health minister Mehmet Müezzinoğlu has said seven people are in a "serious" condition.

Musician Deborah Dyer - aka Skin - has said she is "okay... very shaken" after a suicide bomber struck near the hotel she was staying in in Istanbul.

Posting to Facebook, the Skunk Anansie singer said the building "shook like paper" when the blast went off.

Four people were killed and 36 others injured in the explosion.
