The students gave the ultimatum at a peaceful demonstration at some South African companies in Abuja on Thursday.
During the march the students carried a banner, which read: ‘’NANS Against Xenophobic Attacks on Nigerians.’’
While the students marched, the security men stood and watched to ensure law and order.
The president of NANS, Kadiri Aruna, said in an interview with News Agency of Nigeria (NAN) at DSTV office, a South African company, in Wuse 2, Abuja, that Nigerian students had resolved to condemn the attacks.
Aruna said that the protest would also serve as a warning to other countries trying to underrate Nigerians.
He said that after 48 hours, if nothing was done, messages would be sent to students in all university campuses to bring down MTN masts all over the country.
Aruna said that DSTV and Shoprite would also be affected as the union had put adequate strategies in place to make the action effective.
“All the South African business empires in Nigeria and their collaborators in Nigeria will be affected.
“I don’t want to say we will be barbaric but we will not be lawful in our actions, we will do it and face the consequences, enough of this rubbish,’’ he said.
Aruna stressed that the poor treatment being meted out to Nigerians was particularly insulting given the role Nigeria played in ending the apartheid regime in South Africa.
He said: “Nigeria contributed 80 per cent of the freedom the South Africans are enjoying today because we saved them from the jaws of apartheid.
“Who is South Africa to humiliate Nigeria? So they forget things so soon, let them go back to history and records to see how much financial assistance and what the country did to save them”.
The union president said that the situation was inhuman and for this reason all reasonable Nigerians must react.
He said that the Federal Government should not wait till the dying minute before evacuating Nigerians from South Africa.
Aruna said it was time for government not to only condemn the attacks but take a firm stand by summoning South Africa’s high commissioner and if possible cut diplomatic ties with that country.
