A suicide bomber who killed an officer in a Jan. 6 attack on an Istanbul police station is a Russian citizen with ties to the Islamic State, Turkish newspaper Hurriyet reported Monday.
The report identified the woman as 18-year-old Diana Ramazova of the turbulent republic of Dagestan, who is alleged to have married an Islamic State extremist in Turkey last year.
The pair is said to have travelled to Syria together in July 2014 and fought alongside the Islamic State.
The woman's husband, a Norwegian citizen of Chechen descent identified in the report as Abu Aluevitsj Edelbijev, is believed to have died fighting in Syria in December, at which point Ramazova returned to Turkey.
Turkish police are still investigating the bombing, and two other individuals from Dagestan were detained and questioned in connection with the case, according to widespread Turkish media reports.
Earlier, Turkish media reports identified Ramazova as a Chechen, though Chechnya's Interior Ministry said they had no record of the woman having applied for a passport, the Caucasus Knot website reported.
