A crashed plane is seen in Lakes State, South Sudan Sunday in this picture obtained from social media.
On the casualty figures, Radio Miraya quoted Eastern Lakes minister as confirming the death of 19 passengers with two survivors - the pilot and a young child. The causes of the drama remain for the moment to be determined.
The plane was carrying 22 people when it crashed in South Sudan.
The aircraft was carrying 22 people, 17 of whom died as a result of the accident. "There were people everywhere", the minister said, describing the crash site.
Radio Miraya, a United Nations broadcaster, had earlier reported him dead.
The plane, a South West Aviation Let L-410, was flying from the capital Juba to the city of Yirol with 20 passengers and three crew.
"The whole town is in shock, the shops are closed, some people have taken their relatives for burial", Abel told the AFP news agency.
"The plane crashed and killed 17 people and we have three survivors", Abel told Reuters by phone from Yirol.
"When the plane was landing the weather was foggy and this was not a good situation for plane landing".
Photographs of the sunken wreckage were posted on social media by Radio Miraya, which said a Ugandan national had been identified as one of the dead.
In 2017, 37 people had a miraculous escape after their plane hit a fire truck on a runway in northwestern Wau before bursting into flames. Tens of thousands have died in the fighting and millions have been displaced.
