According to reports by Syrian state news agency SANA, U.S. forces struck a deal with ISIS whereby the terrorist group would give up 50 tons of gold across eastern Syria's Deir el-Zour province in exchange for safe passage.

The precious metal, worth about $2.13 billion, was plundered by the self-designated "caliphate" as its reign of terror spread across Syria and Iraq between 2015 and 2017.

Turkish newspaper Daily Sabah reports that local sources claim U.S. Army helicopters have already transferred the gold from the U.S. forces' base in Kobani, the Kurdish-controlled city that lies close to Syria's northern border with Syria. A portion of the gold was also distributed to the Kurdish People's Protection Units (YPG), which dominates the U.S.-allied Syrian Democratic Forces (SDF).
