The news broke via the Beirut-based Middle East News site Al-Masdar which is well-known for often being the first to report Syria news, given its rare sources in the Syrian military. According to the Al-Masdar report:
According to reports from the Deir Ezzor Governorate, the U.S. Coalition and the SDF both targeted the Syrian government boats with heavy machine gun fire in front of the town of Al-Shuhayl.
Pro-SDF accounts later released photos showing smoke rising from one of the ferries that were targeted by their machine gun fire.
Kurdish media and SDF accounts, along with a number of Middle East analysts also confirmed the incident, which is reportedly the second such attack on government oil supplies in under a month.
Washington has imposed a complete oil and fuel embargo on Syria, which Damascus' close ally Iran has recently sought to circumvent.
Turkish media also confirmed the attack, which according to early reports left four dead.
