The office of MTN in the Bodija area of Ibadan, the Oyo state capital was on Tuesday night set on fire by angry mobs.
Protesters had earlier in the day attempted to vandalise the office but were beaten back by security agents.
But some individuals managed to set the building housing the office ablaze later Tuesday night.
Firefighters arrived the scene late and could not do anything to salvage the building.
They, however, prevented the fire from spreading to other buildings.
Following attacks in MTN offices and other companies affiliated to South Africa across the country earlier in the day, the office was shut for business.
Earlier on Tuesday, one person was shot dead outside the Shoprite premises around Jakande, Lekki area of Lagos state.
The victim was reportedly killed after an angry mob set a police van on fire for preventing them from gaining access into the mall.
There were also reported attacks on MTN and Shoprite facilities across the country in reaction to Sunday’s attacks on foreign nationals, including Nigerians, in South Africa.
The federal government had condemned the attacks and earlier on Tuesday summoned Bobby Moroe, South Africa’s high commissioner to Nigeria, over the incident.
