Johannesburg - An ANC supporter was killed outside a voting station in KwaDukuza, KwaZulu-Natal, on Wednesday, the party said.
The person was allegedly killed by a member of an opposition party, African National Congress spokesperson Jackson Mthembu
said in a statement.
KwaZulu-Natal police spokesperson Captain Thulani Zwane said the shooting took place outside the Lindelani voting station at about 21.30.
According to Jackson, "this comrade was killed while sitting at the ANC desk outside a voting station".
Electoral Commission of SA (IEC) spokesperson for the province Thabani Ngwira said he had not heard of the incident.
The ANC called on the IEC and police to urgently investigate the matter.
"This killing is clearly calculated to undermine free and fair elections."
However, Zwane said the motive for the attack was unknown and police were investigating.
He appealed to ANC supporters to exercise restraint.
Earlier, acting Government Communication and Information System CEO Phumla Williams
said in a statement two deaths outside polling stations were recorded on Wednesday but did not provide further details.
She said 97 people were arrested for offences related to Wednesday's general elections.
