A Valan Air Cargo Antonov AN-26, registration ER-AVB performing a charter freight flight from Ouagadougou (Burkina Faso) to Abidjan (Cote de Ivoire) with 4 crew and 6 passengers, was on approach to Abidjan's runway 03 at 09:45L (09:45Z) in poor weather when the aircraft came to a stop in the sea about 650 meters/2130 feet ahead of the runway threshold. Four occupants were killed, six occupants were taken to hospitals with injuries.
Initial reports by the airport had suggested the aircraft had just attempted to depart but overran runway 21.
Later emergency services reported the aircraft was arriving from Burkina Faso on approach from the sea side in thunderstorms, gusting winds and lightning when the aircraft ended up in the waters ahead of the runway.
Cote de Ivoire's Minister of Interior reported there were 4 fatalities and 6 injured. 6 occupants were Moldovans, 4 were French, all French are amongst the survivors.
According to the aircraft registry by the CAA Moldova (list compiled on Oct 10th 2017) Valan Air operates AN-26s with the tailnumbers ER-AVA, ER-AVB and ER-AZO.
Initial UK news report indicated that the aircraft came down after take off but these were clearly erroneous as noted in the Avherald report.
It looks like the aircraft landed short of the runway during a bad weather approach to land. Windshear?
