A female suicide bomber has blown herself up in the Turkish city of Istanbul, injuring two police officers, the city governor says, the BBC reports.
She hit a police station in the tourist hub of Sultanahmet. Reports say one of the officers has died of his injuries.
Governor Vasip Sahin told Turkish TV that the woman spoke English with “a thick accent”, but her nationality and identity remained unknown.
No group has yet said it was behind the attack, the second on police in a week.
Police arrested a man who threw grenades and fired a weapon at officers near the prime minister’s office last Thursday, but no-one was injured in the attack.
The bomber in the latest incident was reported to have died in the attack.
Police have sealed off an area in the historic district, where the Blue Mosque and the Hagia Sophia museum are located.
Mr Sahin said the woman entered the station and told police she had lost her wallet before detonating the bomb.
“Right now one police officer is in hospital in a critical condition and another is lightly injured… The female bomber lost her life.”
The banned Marxist DHKP-C group said it was behind the earlier attack in the city on 1 January, which took place outside Dolmabahce Palace.
