A devastating plane crash in South Sudan’s Unity State has left 20 people dead, according to officials. The small aircraft, which was carrying oil workers, went down on Wednesday morning near the Unity oilfield airport. It was en route to the capital, Juba, when the tragedy occurred.

Authorities confirmed that the passengers were employees of the Greater Pioneer Operating Company (GPOC), a group that includes major players like China National Petroleum Corporation and Nile Petroleum Corporation. Among those killed were two Chinese nationals and one Indian.

Initially, reports suggested 18 deaths, but officials later updated the toll after two survivors succumbed to their injuries. Only one person survived the crash.

This incident adds to a string of aviation disasters in South Sudan, a country still grappling with the aftermath of years of conflict. In 2018, a similar crash near Yirol claimed 19 lives, while a 2015 cargo plane accident in Juba left dozens dead.

Details about what caused the latest crash remain unclear, leaving families and colleagues in shock. Investigations are likely underway as the nation mourns yet another heartbreaking loss.
