Islamic State behind Kenya's Mombasa attack by robed women

Islamic State supporters carried out an attack on Kenya's port city of Mombasa in which three robed women tricked their way into a police station, stabbed an officer and ignited a petrol-bomb in the building, the group's Amaq news agency said on Tuesday.

Militant attacks, mostly claimed by al Shabaab militants from neighbouring Somalia, have increased in recent years in Kenya, which has a large Muslim population concentrated mostly along its Indian Ocean coast.
