The dead included 10 women, five men and one juvenile. They were among worshippers at one of the churches the gunmen attacked, said Phillip Ndolo, a senior police official.

So far the death toll has risen to 16 and more than 40 have been injured. The injured are being treated at various hospitals, Ndolo said, adding that the gunmen first killed two policemen screening the worshippers.
