The bombing took place in a police station near the famed Blue Mosque and Hagia Sofia museum in Istanbul's Sultanahmet tourist area, parts of which were cordoned off for an investigation, Turkish media reported.
The woman was attempting to enter the police station near Sultanahmet Square on the pretext of having left her wallet inside when guards stopped her at the entrance, Istanbul Gov. Vasif Sahin told reporters Tuesday. She spoke heavily accented English, Sahin said.
Two officers were hurt in the bombing, and one of them later died of his injuries, authorities said.
Authorities secured the blast area and halted public transportation into the neighborhood, the Hurriyet Daily News reported.'
