Air Zimbabwe only resumed flights in September after pilots staged a work boycott that lasted two months from July.
Well placed sources at the state-run airline said fuel suppliers had stopped supplying jet AI to Air Zimbabwe as they were owed outstanding payments for some deliveries.
The sources said Air Zimbabwe is now only servicing local and regional routes such as Harare-Johannesburg and Harare-Lubumbashi and Lusaka. International flights which were cancelled as a result of the fuel shortages include the Harare-London flight and the Harare-China flight.
The airline will only resume flying to these two destinations once it secures adequate fuel supplies.
The fresh challenge is likely to impact on the airline’s already battered reputation.
Once considered as one of the best airlines in Africa, Air Zimbabwe has been run down due to successive years of mismanagement, corruption, political interference and inadequate funding.
