United States military aircraft for the first time attacked hundreds of trucks on Monday that the extremist Islamic State (IS) group had been using to smuggle the crude oil it has been producing in Syria, US officials said.
According to an initial assessment, 116 trucks were destroyed in the attack, which took place near Deir al-Zour, an area in eastern Syria that is controlled by IS. The air strikes were carried out by four A-10 attack aircraft and two AC-130 gunships based in Turkey.
Plans for the strike were developed well before the terrorist attacks in and around Paris on Friday, officials familiar with the operation said, and were part of a broader operation to disrupt the ability of IS, also known as Isis or Isil, to generate revenue to support its military operations and govern its territory.
US officials have long been frustrated by the ability of IS to generate tens of millions of dollars a month by producing and exporting oil. To disrupt that source of revenue, US officials said last week that the US had sharply stepped up its air strikes against infrastructure that allowed IS to pump oil in Syria.
Until Monday, the US had refrained from striking the fleet used to transport oil, believed to include more than 1,000 tanker trucks, because of concerns about causing civilian casualties. As a result, IS’s distribution system for exporting oil had remained largely intact.
The new campaign is called Tidal Wave II. It is named after the second World War effort to counter Nazi Germany by striking Romania's oil industry.
Lieut Gen Sean B MacFarland, who in September assumed command of the international coalition's campaign in Iraq and Syria, suggested the name.
Strafing runs
To reduce the risk of harming civilians, two F-15 warplanes dropped leaflets about an hour before the attack warning drivers to abandon their vehicles, and strafing runs were conducted to reinforce the message. The area where the trucks assemble in Syria has been closely monitored by reconnaissance drones.
As many as 1,000 trucks have been observed there, waiting to receive their cargo of illicit oil. On Monday, 295 trucks were in the area, and more than a third of them were destroyed, US officials said. The A-10s dropped two dozen 500-pound bombs and conducted strafing runs with 30mm Gatling guns. The AC-130s attacked with 30mm Gatling guns and 105mm cannon.
The pilots saw several drivers running to a nearby tent and did not attack them, a US official said, and there were no immediate reports of civilian casualties.
Col Steven H Warren, a Baghdad-based spokesman for the US-led coalition, confirmed that A-10s and AC-130s had been used in the attack and that 116 tanker trucks had been destroyed.
“This part of Tidal Wave II is designed to attack the distribution component of Isil’s oil- smuggling operation and degrade their capacity to fund their military operations,” he said.
The strike came just days after Kurdish and Yazidi fighters, backed by US air strikes, cut an important road, Highway 47, that IS has used to move supplies and fighters between Syria and Mosul, Iraq’s second-largest city, which was captured by the militant group last year.
That road was cut on Thursday, and Kurdish and Yazidi fighters retook the Iraqi city of Sinjar the next day.
The US operation against the oil trucks followed a French raid on Sunday on two Islamic State targets in Raqqa, Syria, which allied officials identified as a headquarters building and a training camp.
More than 20 bombs were dropped by French aircraft in the attack, an allied official said. It was not clear how much damage was caused, and no secondary explosions were observed.
