Fire at the South African parliament has broken out again after a lull, the fire brigade reportedly said.
"The fire restarted in the roof of the building housing the national assembly," the fire brigade's spokesman Jermaine Carelse said, quoted by AFP.
Only a dozen firefighters were still at the scene, he added.
"Devastating. Distressing. Inexplicable..." parliamentary spokesman Moloto Mothapo tweeted.
Earlier, police arrested and charged a person suspected of arson.
"Man (49) allegedly linked to setting Parliament building alight to appear in court on 04/01 on charges of housebreaking and theft, arson and will also be charged under The National Key Point Act,” the police tweeted.
The parliament sits in a complex of buildings - an old building dating back to the 19th century and new ones from the 1920s and 1980s that are used by the lower house.
