Police in South Africa say four white men face treason and terrorism charges over a plot that included plans to attack the ongoing African National Congress political party convention.

Brig. Billy Jones told The Associated Press on Tuesday that the men were arrested in different locations in South Africa on Sunday. Police confirmed they made the arrests Monday, but offered contradictory information about the men's proposed target.

The men were scheduled to appear before a judge Tuesday in a Bloemfontein court. That's where the ANC is holding its Mangaung convention to pick the party's leadership.

Police have described the white men as having "right-wing" political beliefs, but offered no other details about them. Some fringe groups support a return of racist apartheid rule in the country.
