The plane, carrying President Felix Tshisekedi’s driver, a logistics manager and some soldiers, was headed for the capital Kinshasa and went off radar on Thursday afternoon, an hour after departing, a statement from the civil aviation authority said.
It crashed in a forest in Maniema and broke up upon landing.
“There are no survivors. The bodies were all burnt to ashes,” said advisor Vidiye Tshimanga.
The cause of the accident was not yet clear.
No information immediately backed up such a claim.
