Authorities in Johannesburg, South Africa's commercial hub, have blamed the ongoing heatwave for the lack of water in some parts of the city for several weeks.

The public water services provider says increased water consumption and lower reservoir levels are also fuelling the city's ongoing water crisis.

Water shortages are common in Johannesburg, and have triggered protests in the past.

The current water crisis began late last year but has worsened in recent weeks.
