A heavy police and military presence has been deployed in Western Cape townships following sporadic xenophobic violence, police said on Monday.
Provincial authorities said scores of foreigners had sought refuge at police stations in the region.
Police spokesperson Captain Frederick van Wyk said that on Sunday night there were "sporadic incidents of looting" at shops belonging to foreigners.
Areas where this occurred included Nyanga, Philippi East and Khayelitsha on the Cape Flats, Wellington, Paarl East, Mbekweni (a Paarl township), Franschhoek and Klapmuts.
"Police responded and a heavy police contingency was deployed in conjunction with Metro Police and SANDF in all these areas," Van Wyk said.
He said seven men, aged between 19 and 30, had been arrested in the Nyanga area.
They were charged with public violence and would appear in the Phillipi Magistrates' Court on Monday.
"SAPS will continue to deploy in high numbers to maintain law and order in the mentioned areas," he said.
"Tranquillity has been restored and no further reports of violence have been reported."
Spokesperson for provincial disaster management Daniella Ebenezer said earlier that 70 foreigners had sought refuge overnight at Mbekweni police station in Paarl and 22 at Wellington.
There were smaller numbers at police stations in Franschhoek, and Langa and Harare on the Cape Flats.
They had gone to the stations "mainly because they were fearful", but in some instances following attacks on shops.
Ebenezer said there were "sporadic" attacks on shops on Saturday in the region, and "some incidents of looting" on Sunday.
No-one had been seriously injured.
She said that according to reports from police, on Sunday spaza shops and containers also used as shops were "damaged" in Mbekweni, Paarl East, Wellington and Nyanga.
The province and municipalities were ready with contingency plans, she said.
Die Burger newspaper reported on Monday that shortly before midnight on Sunday, police advised foreigners, mainly Somalis, to leave the Cape Flats township of Nyanga, and escorted numbers of them out of the area.
The newspaper carried a photograph of Somali spaza shops in flames in Philippi, also on the Cape Flats. - Sapa
