Two men convicted of assassinating anti-apartheid communist leader Chris Hani have survived a prison attack after an inmate stabbed them with a spoon.
"Offenders Clive Derby-Lewis and Janus Walusz were attacked by one offender with a 'kitchen table spoon'," said correctional services spokesman Manelisi Wolela, without elaborating.
"They both suffered some lacerations in their heads and hands at the Kgosi Mampuru Correctional Centre" in the capital Pretoria, he said in a statement.
Right-wing former MP Derby-Lewis, 78, and Polish immigrant Walusz, 61, are serving 25 years for shooting dead South African Communist Party leader Hani in front of his home in 1993.
The death of the charismatic and hugely popular leader came at a crucial point in political negotiations to end white minority apartheid rule, and many feared it would push the country over the edge.
The assassination pushed racial tensions to near-breaking point, prompting riots and deaths that pushed late liberation leader Nelson Mandela to call for peace in a nationally televised address.
Mandela became South Africa's first black president following the first all-race elections a year later.
Derby-Lewis and Walusz have remained controversial figures, and past talk of parole has drawn fierce opposition from both the public and Hani's family.
