South African television reporter mugged on camera
The video, which was posted on the Internet, shows the men pacing around reporter Vuyo Mvoko while he speaks to the camera, before a scuffle ensues, and then Mvoko is heard shouting: "Hey, we're being mugged."
"He was looking for the phone and when I wasn't giving him the phone, he calls the other one who has a gun, to say: 'shoot this dog' or something like that," Mvoko, who works for the national broadcaster, told radio station 702 on Wednesday.
"So I gave him the phone."
The incident is just one of scores of often violent crimes, including rape, robberies, and murder, recorded every day in South Africa, earning it a place among the most violent countries in the world outside a war zone.
Zambia's Lungu, 58, is in South Africa for medical tests after he fell ill at the weekend with a suspected narrowing of the food pipe.
