A cargo plane has crashed on take-off near the international airport in South Sudan's capital Juba.
According to local reports, nearly 40 bodies have been counted at the wreck site with many casualties being reported.
It is unclear how many of the victims were on the plane and how many were on the ground.
Juba's Radio Miraya says the Russian-built plane was heading to Paloch in Upper Nile State and crashed just 800m (half a mile) from the runway.
Presidential spokesman Ateny Wek Ateny told Reuters news agency that there were at least two survivors, a crew member and a child on board.
