The death toll from a mass shooting at a tavern west of Johannesburg, South Africa, has risen to 18, following the death of another victim in hospital, police said on Monday.
The shooting occurred late Saturday when eight gunmen armed with assault rifles stormed a bar in Wedela, a semi-rural township about 80 kilometres from central Johannesburg.
Police said 13 men and four women were initially killed in the attack, while another victim later died in hospital.
Only four of the victims have so far been identified. Police said two were South Africans and two were nationals of neighbouring Lesotho.
The motive for the attack remains unclear. However, the area is reportedly affected by rivalry among gangs involved in illegal gold mining.
Thousands of unregistered miners operate in abandoned mine shafts across South Africa, with many coming from other southern African countries, including Lesotho. The illicit mining sector has been associated with organised crime and other violent activities.
The Johannesburg-area shooting was part of a bloody weekend in South Africa. In a separate incident on Sunday, 10 people were killed and 11 others wounded when gunmen opened fire at an entertainment venue in a township outside Cape Town.
South Africa has a high rate of gun violence, with shootings frequently linked to gang disputes, extortion and competition between informal businesses.
