Three women have been killed after trying to stage an attack at the main police station in the Kenyan port city of Mombasa, officials say.
The women, wearing hijabs, entered the station saying they wanted to report a crime, police say. One of the women pulled a knife and another threw a petrol bomb, starting a fire. Two officers were injured.
It is not clear who is behind the attack, but Islamist group al-Shabab has staged numerous attacks in Kenya. The Somali-based group has been targeting Kenya since 2011, when Kenyan troops were deployed to rid Somalia of the militants.
