Three men armed with guns and knives slit the throats of three worshippers at a mosque near Durban in South Africa and a person was killed, an emergency service official said on Thursday.

One victim jumped from a side window of the building, which had been set ablaze sending smoke billowing, said Prem Balram, a spokesman for Reaction Unit SA, a private emergency service, who was among the first on the scene.
