Twelve killed in mass shooting in Johannesburg, police say

At least 12 people have been killed in a mass shooting in an area of Johannesburg, police in South Africa say.They say another nine people were injured in the attack at an informal settlement in Cleveland late on Tuesday, and a manhunt for suspects is under way."It is alleged that more than 10 suspects were dropped off by a white Toyota Quantum near a petrol station in Cleveland," the police said in a statement."The suspects allegedly entered the informal settlement through both entrances and moved through the area, opening fire on residents and community members at multiple locations before fleeing the scene in the same vehicle," the statement added.South Africa has one of the highest murder rates in the world, with around 60 people killed per day on average.Shootings in informal settlements are highly common in the country and are sometimes linked to gang violence and personal disputes.The local police department said its officers responded to a "complaint of shooting in progress" at about 23:10 local time on Tuesday (21:10 GMT).Emergency medical services were also deployed to treat the injured.
