Terror group claims Istanbul New Year massacre, attacker on the run

The statement by the extremist group -- which Turkey is fighting in neighbouring Syria -- was the first undisputed claim it has made for an attack in Turkey despite being blamed for several assaults over the last year.

Anti-terror police made their first arrests over the attack, which unleashed scenes of panic among party-goers at one of Istanbul's swankiest venues and killed mostly foreign tourists.

The shooting took place just 75 minutes into 2017 after a bloody year in Turkey in which hundreds of people were killed in violence blamed on both IS jihadists and Kurdish militants.

In a statement circulated on social media, the jihadist group said one of the "soldiers of the caliphate" had carried out the attack on the Reina nightclub.

It accused Turkey, a majority-Muslim country, of being a servant of Christians, in a possible reference to Ankara's alliance with the international coalition fighting IS in neighbouring Syria and Iraq.

'Continue with determination'

The IS statement said the attack was in response to Turkey's military intervention against the jihadists in war-ravaged Syria where Turkish troops are pressing on with a four-month incursion to oust IS jihadists the border area.

Turkey is also spearheading a ceasefire plan with Russia to form a basis for peace talks on Syria.

But after a cabinet meeting in Ankara chaired by President Recep Tayyip Erdogan, the government vowed that the operation in Syria, dubbed Euphrates Shield, would continue.

"This was a message for our cross-border operations, above all the Euphrates Shield," said Deputy Prime Minister Numan Kurtulmus.

"We will carry on our cross-border operations and Euphrates Shield and with determination," he added.

After a lightning successful start to the operation recapturing towns from IS including Jarabulus, the Turkish military has taken dozens of casualties as it tries to capture Al Bab where IS has put up a stronger fight to remain in control.

'Danger continues'

Arriving by taxi at the plush Reina nightclub on the shores of the Bosphorus, the gunman produced a weapon, reportedly a Kalashnikov, and shot dead a policeman and civilian at the entrance.

He then fired off four magazines containing a total of 120 bullets around the club which was filled with an estimated 700 people. Terrified guests flung themselves into the freezing waters of the Bosphorus in panic.

But after changing clothes, the gunman left the nightclub in the ensuing chaos and has managed to evade security forces.

There were no reports that security services had come close to detaining the gunman but Kurtulmus said physical and fingerprint data had been obtained.

"It is a difficult investigation," he said, vowing to "speedily" identify the attacker and "if there are outside supporters and the forces behind them".

Kurtulmus said anti-terror police have detained eight suspects. But there was no indication of their relationship to the attacker and the minister did not comment on the IS claim.

Hurriyet daily said investigators believe the gunman may be from the Central Asian states of Kyrgyzstan or Uzbekistan.

The attacker may be linked to the same cell that in June carried out a triple suicide bombing and gun attack at Istanbul's Ataturk airport blamed on IS that left 47 people dead, the paper added.

But pro-government daily Yeni Akit caused a furore on social media with a headline declaring the United States was the "number one suspect" over the attack.

'Panicking and blood'

Twelve Turks were killed in the attack alongside 27 foreigners, including one Belgian-Turkish dual national. Sixty-five people were wounded.

The foreigners who died -- most of them from Arab countries and including Muslims -- had come to the club to celebrate a special night in style.

They included three Lebanese nationals, two Jordanians and three Iraqis, officials in their respective countries said. At least one German was killed.

A Canadian woman, a Russian woman and a teenage Arab Israeli were also among the dead. Turkish press reports said at least seven Saudi nationals died but this has yet to be confirmed by Riyadh.

The attack evoked memories of the November 2015 carnage in Paris when IS jihadists unleashed a gun and bombing rampage on nightspots in the French capital, killing 130 people including 90 at the Bataclan concert hall.

"I think back to those moments, I can't erase them from my memory," survivor Yusuf Kodat from Alsace in France told AFP as he returned to the scene of the attack by the Bosphorus.

"The people panicking, the blood, the noise of the gunshots, the explosions. That's what I keep on thinking about," Kodat said.
