Mpumalanga police have activated a 72-hour plan after a shooting in which two men were killed and a woman critically injured on the Nyongane Main Road in Hazyview on Tuesday.
Police spokesperson Lt-Col Jabu Ndubane said preliminary investigations indicate four people were travelling on the road towards Nyongane when they were ambushed by an unknown number of suspects hiding in bushes.
The suspects, who were on foot, allegedly approached the vehicle and opened fire at close range, Ndubane said.
