MTN calls for calm amid rising tensions in SA, Nigeria
MTN has called for people to exercise restraint and remain calm.
It comes amid reports of an attack on one of its offices in Abuja in Nigeria.
Nigerian media are reporting that a group of people were protesting against xenophobic attacks in South Africa when they turned violent.
The telecoms company however has not provided any details of the incident.
In a statement, MTN says: "Reacting to recent events that appear to be directed against non-nationals both in South Africa and Nigeria, MTN Group expresses concern over the violence. MTN requests people to exercise restraint and remain calm."
Photos have emerged of what appears to be an MTN office which had been vandalised during the protests.
A contentious march against foreign nationals is expected to take place in Tshwane tomorrow.
Police say security measures have been put in place ahead of the march.
National police spokesperson Vish Naidoo says: "Members of law enforcement will be deployed along the route and at the venue where memorandums are expected to be handed over to identified recipients. Their mandate will be to maintain peace, safety and stability and to prevent crime."
He urges participants to remain peaceful.
"While members of the security forces are urged to exercise maximum restraint while carrying out their duties, criminal behaviour will not be tolerated under any circumstances."
