US, allies hit Islamic State's oil refineries in Syria

Pentagon gives no details on the attacks, nor does it specify which countries were involved

The Pentagon said the US and its Arab allies are launching more airstrikes into Syria against Islamic State militants.

Pentagon spokesman Navy Rear Adm. John Kirby told CNN Wednesday that US and coalition forces hit 12 targets, including oil refineries that were providing up to $2 million a day in income to the Islamic State group.

Pentagon officials told AFP that aircraft from Saudi Arabia and the United Arab Emirates took part in the latest round of US-led bombing raids against Islamic State jihadists in Syria.

The strikes are a continuation of the broader military campaign that began Monday against the militant group. Four Arab nations — Bahrain, Saudi Arabia, Jordan and United Arab Emirates — participated in those strikes, and Qatar supported the attacks.

The Pentagon released no details on the strikes, but said the operation was continuing.

As of Tuesday, according to US Central Command, the US had conducted airstrikes that hit at least 20 locations in Syria. Combat aircraft flew 64 sorties.
