A cargo plane with passengers on board has crashed on take-off at the main airport in Juba, the capital of South Sudan.
There are reports from the scene of many casualties.
Eyewitnesses say at least 40 bodies have been recovered from the site of the crash, which is only 800 metres from the end of the runway.
There are thought to be at least two survivors, a member of the crew and a child.
It is not clear how many were on the Russian-built aircraft and how many on the ground. Local fishermen were in the area at the time.
The plane is thought to have been heading for Paloch in Upper Nile State.
