ANC president Jacob Zuma has called for South Africa's immigration laws to be fine-tuned to be able to work effectively - and for service delivery to be speeded up to avoid xenophobic violence.
Speaking at the signing of a memorandum of understanding between the ANC and the Indian National Congress (INC), Zuma suggested that immigration laws were not being properly applied to process illegal immigrants.
He signed the agreement with INC president Sonia Gandhi in New Delhi yesterday.
"We concede that some remedial action is needed in the implementation of our immigration laws, and also to improve service delivery, which may have led to frustrations among some of our people.
"However, we remain convinced that no service delivery bottlenecks could justify that type of violent action we saw last month," said Zuma.
He said the ANC was working hard to ensure that lasting solutions were found.
"The response should address the perceptions about immigrants and, on the other hand, intensify the fight against crime.
"It is clear that criminals took advantage of the situation, if some did not actually instigate some of the incidents," he said.
Zuma also condemned the use of violence by Zanu-PF and its supporters against members of the opposition Movement for Democratic Change.
"We are alarmed and anxious about the reports of violence.
"If these are accurate, the violence surely puts enormous strain on the preparations for the presidential election run-off."
He urged all parties to abide by SADC requirements for peaceful elections in Zimbabwe.
"We cannot rest until the situation is resolved, as it affects all of us. We want to see the return of peace and stability in Zimbabwe as speedily as possible."
