BLOEMFONTEIN, South Africa, Dec 17 (Reuters) - South African police said on Monday they had foiled a plot by suspected right-wing extremists to bomb a major meeting of the ruling African National Congress (ANC).
Four men, aged between 40 and 50, were arrested on Sunday, the police said in a statement.
"They planned to plant a bomb in one of the tents," national police spokesman Phuti Setati said.
Close to 5,000 ANC members, including President Jacob Zuma, government ministers and top business people are attending the conference in the central city of Bloemfontein under heavy police presence.
Police have not issued more details of the alleged plot, but said the suspects would would be charged and appear in court.
The few vehicles that were being allowed onto the university campus hosting the meeting were being scanned by police and sniffer dogs.
In July, a former university lecturer was found guilty of orchestrating a 2002 plot aimed at assassinating former president Nelson Mandela, overthrowing the ANC and driving South Africa's black majority out of the country. (Reporting by Peroshni Govender; Editing by Ed Cropley)
