On 6 January 2015, Diana Ramazova from Dagestan detonated a bomb vest at a police station in Istanbul's central Sultanahmet district, near the Blue Mosque and Hagia Sophia.

Istanbul governor Vasip Sahin said the woman, who reportedly spoke English with "a thick accent" and was dressed in a niqab, entered the police station and told officers she had lost her wallet before detonating the bomb.

[2] Turkish Prime Minister Ahmet Davutoğlu told reporters that the bomber was carrying two other devices, which were safely defused by officers on the scene.

[4] On January 7, the far-left armed group Revolutionary People's Liberation Party–Front (DHKP/C) claimed responsibility for the attack, saying it was meant "to punish (the) murderers of Berkin Elvan" and "to call to account the fascist state that protects AKP's corrupt, stealing ministers".

[3] The bombing came five days after another member of DHKP/C attacked police on guard outside the Ottoman-era Dolmabahçe Palace, hurling two grenades that failed to explode.
