Four people have been killed and eight wounded in a bar in eastern South Africa after two men fired indiscriminately at customers, police said, on the same night as a bar shooting in Soweto left 15 dead.

Police were trying to verify if the attacks were linked, they said, noting their similarity.

In the city of Pietermaritzburg in KwaZulu-Natal province on Saturday night, two entered the bar and “fired random shots at the patrons” before fleeing, local police spokesman Nqobile Gwala said.
