Authorities in Namibia have confirmed a family of four German tourists and their pilot were killed when their plane crashed Tuesday during take-off in the country’s northern Zambezi Region.

Namibia’s Ministry of Works and Transport says it is investigating what caused the six-seater Cessna 210 to crash shortly after take-off, killing all five people on board.

The ministry says the plane crashed on Tuesday afternoon near Impalila Island, on the Zambezi river in the Kavango–Zambezi Transfrontier Conservation Area.
