Photo: Daily Mavrick Netcare 911 spokesperson Shawn Herbst has told News24 that, according to information he had received from the scene, 2 000 litres of diesel had leaked from a generator on the 15th floor.
"Many people have been evacuated, but others are still trapped on the 17th floor. Our paramedics can't get to them and they can't come down because of the fumes. We are waiting for the fire department to assist."
Herbst said no fires had been reported.
This is a developing story.
