A deadly fire in Johannesburg's inner city was "a wake-up call" for South Africa, says President Cyril Ramaphosa, APA reports citing BBC.
Seventy-four people were killed - including 12 children - after a blaze in a five-storey building, which was being occupied by homeless people.
More than 50 others were injured.
Earlier, the city of Johannesburg confirmed it owned the building, but said cartels had taken it over. Officials say the cause of the deadly fire is unclear.
In a news conference at the site of the fire, Mr Ramaphosa said the incident needed to be investigated and lessons learnt to prevent future tragedies.
