Turkish authorities detained three Russian nationals suspected of links with Daesh following a suicide bomb attack in Istanbul that killed 10 tourists, media reports said on Wednesday.
A suicide bomber thought to have crossed recently from Syria killed nine German and one Peruvian tourists on Tuesday in Istanbul's historic Sultanahmet Square, a major tourist draw, in an attack Turkey blamed on Daesh. Fifteen people were also hurt in the attack.
Russia's Consulate General in the Mediterranean city of Antalya said three Russians had been detained over suspected connection to Daesh, Russian state news agency RIA said.
Police also seized documents and CDs during a search of the premises where the suspects were staying, Turkey's Dogan News Agency said. It was not immediately clear when the detentions occurred.
There was no immediate claim of responsibility for the Istanbul blast but Islamist, leftist and Kurdish militants, who are battling Ankara in southeast Turkey, have all carried out attacks in the past.
Prime Minister Ahmet Davutoglu said he spoke with German Chancellor Angela Merkel to offer condolences and vowed Turkey's fight against Daesh, at home and as part of the U.S.-led coalition, would continue.
Turkey has become a target for Daesh, with two bombings last year blamed on the radical group, in the town of Suruc near the Syrian border and in the capital Ankara, the latter killing more than 100 people.
