A Kenyan lawyer says a controversial Muslim cleric facing terror-related charges has been killed.

Mbugua Mureithi said Monday that Aboud Rogo was shot dead by unknown assailants as he drove with his family in the coastal city of Mombasa. Rogo's father Abdallah Ali was in the vehicle and said Rogo's five-year-old daughter witnessed the shooting. Rogo's wife also was shot, in the leg.

In January Rogo was charged for possession of a cache of guns, ammunition and detonators. Rogo also faced charges of membership in an al-Qaida-linked Somali militia group which has been outlawed in Kenya. Police charged that Rogo was planning to bomb Kenyan targets over Christmas.

Rogo was acquitted on murder charges for the 2002 bombing of a tourist hotel which killed more than 12 people.
