Seventy men arrested during a raid on a mosque in the Kenyan port city of Mombasa were formally charged Wednesday with being members of Somalia's Al-Qaeda-linked Shebab rebels, officials said.

Kenyan police raided Mombasa's Musa mosque on 2 February, detaining scores of suspects whom they accused of attending a radicalisation meeting. The raid sparked riots in Mombasa in which three people were stabbed.
