ISTANBUL (Reuters) - A suicide bomber blew herself up inside a police station in Istanbul's historic Sultanahmet district on Tuesday, killing one officer and wounding another, the city's governor and Turkish media said.

The woman spoke English as she entered the building but her nationality and identity were unknown, Governor Vasip Sahin told reporters at the scene.

Turkish media said one of the officers died from his wounds.

Could be PKK, a Kurdish teen was killed last week by Turkish police.
