Zimbabwe’s state-owned electricity company, Zesa, has cut its supply to major users because of unpaid bills worth $77m (£60m) .
The firm said mining, agriculture and domestic users should settle their bills quickly to prevent prolonging the cuts.
According to official figures, Zimbabwe is generating less than half its peak electricity demand.
Power shortages have been exacerbated by a recent severe drought which reduced water levels in Zimbabwe’s biggest hydro-plant. BBC World Service
