A vessel carrying 95 people sank on Zimbabwe’s Lake Kariba, with the death toll climbing to at least 44 as the day progressed, according to the BBC.

The vessel is said to have overturned after being hit by strong waves, the BBC reported. No further details about the exact cause or circumstances of the capsizing were provided in the available reporting.

The scale of the disaster became clearer over several hours. An early BBC report noted the vessel had sunk with 95 people on board, before a subsequent update put the death toll at least 15. A later report raised that figure to at least 44.

The BBC referred to the vessel as a ‘boat’ in its earlier reports and as a ‘ferry’ in a later update. The available reporting did not specify the number of survivors, the fate of those still unaccounted for, or details of any rescue operation underway.

As reporting on the incident was still developing, the final toll and the full circumstances of the sinking remained unconfirmed in the sources available.
