Protesters in a city in South Africa’s north east blocked roads including a highway linking the country to Mozambique with trucks Wednesday morning as they demonstrated against fuel prices rising to a new record. The road between Mbombela, 350 km east of Johannesburg, and White River has been obstructed by parked trucks, as is the N4 highway connecting the city to the border with Mozambique and the port of Maputo, Callum MacPherson, regional operations manager at Hi-Tech Security Nelspruit, said by phone. There is also a group of protesters moving around the blockades, he said.
