The luxury jet touched down in Juba, the capital of South Sudan, on a mission to collect hundreds of pounds of illicit gold.

On board was a representative of a ruthless paramilitary group accused of ethnic cleansing in Sudan’s sprawling civil war, the flight manifest showed. The gold itself had been smuggled from Darfur, a region of famine and fear in Sudan that is largely under his group’s brutal control.

Porters grunted as they heaved cases filled with gold, about $25 million worth, onto the plane, said three people involved with or briefed on the deal. Airport officials discreetly maintained a perimeter around the jet, which stood out in the main airport of one of the world’s poorest countries.

After 90 minutes, the jet took off again, landing before dawn on March 6 at a private airport in the United Arab Emirates, flight data showed. Its gleaming cargo soon vanished into the global gold market.

As Sudan burns and its people starve, a gold rush is underway.

War has shattered Sudan’s economy, collapsed its health system and turned much of the once-proud capital into piles of rubble. Fighting has also set off one of the world’s worst famines in decades, with 26 million people facing acute hunger or starvation.

But the gold trade is humming. The production and trade of gold, which lies in rich deposits across the vast nation, has actually surpassed prewar levels — and that’s just the official figure in a country rife with smuggling.
