According to authorities, shooting occurred inside a hostel in the KwaMashu area, north of Durban, South Africa, leaving four civilians dead.
“It is reported that at least 20 armed suspects stormed into the hostel and opened fire to the victims,” said Robert Netshiunda, a police spokesperson in the coastal province of KwaZulu-Natal.
Five more people with gunshot wounds were rushed to a clinic, he added.
On Sunday, eight persons were killed in a birthday party shooting in Kwazakele, Gqeberha, with three more civilians injured.
South Africa has one of the world’s highest murder rates, with around 20,000 people killed every year out of a population of 60 million.
The country last year saw string of shootings, fueled by gang violence and alcohol, that killed nearly two dozen at separate bars in working class suburbs in Johannesburg and in the eastern city of Pietermaritzburg. In July, gunmen killed 19 people in random shootings within hours of each other.
According to campaign group Gun Free South Africa, there are about 3 million guns registered in the country, though there are many more unregistered.
Police Minister Bheki Cele, the national police commissioner Fannie Masemola, and crime experts were scheduled to visit the scene of the attack later Monday morning.
