"The doctors were doing assessments yesterday [Monday] and whatever needs to be done in terms of medical care, and they continue to do so," spokesman Joe Maila said.

"They all have different kinds of injuries, different levels of injuries."

The injured were admitted to the Steve Biko Academic Hospital in Pretoria on Monday shortly after arriving in the country.

Maila was unable to specify what sort of injuries they had, or how many of them had to undergo surgery.

Earlier, the SABC reported that 10 of the injured had undergone surgery on Monday night. It reported that most of them had sustained fractures.

Around 115 people, among them 84 South Africans, were killed and dozens trapped when the multi-storey guesthouse attached to the Synagogue Church of All Nations, run by Nigerian preacher TB Joshua, collapsed on Friday, September 12.

Some 350 South Africans were thought to be visiting the church in Lagos when the building came down.

Joshua, one of Nigeria's best-known evangelical preachers referred to by followers across the world as "The Prophet" or "The Man of God", has pledged to go to South Africa to meet survivors and their families.
