ISIS-held oil refinery in Syria hit by U.S.-led strikes, locals say

SANILURFA, Turkey - Residents of a Turkish border town say that U.S.-led coalition warplanes have struck an oil refinery controlled by the Islamic State of Iraq and Syria.

They say the airstrikes hit the Tel Abyad refinery in the early hours of Sunday, a few hundred yards from the Turkish town of Akcakale.

"There was an explosion and I jumped out of bed," said Akcakale businessman Mehmet Ozer.

The U.S.-led coalition has been targeting oil installations controlled by the militants, aiming to cripple revenue sources for the Islamic State of Iraq and Syria (ISIS, also known as ISIL,) estimated at some $3 million a day.

The United States and five Arab allies launched an aerial campaign against ISIS fighters Tuesday with the aim of rolling back and ultimately crushing the extremist group, which has created a proto-state spanning the Syria-Iraq border.

On Saturday, U.S. Central Command said airstrikes targeted ISIS militants attacking a town near the Turkish border for the first time, as well as positions in the country's east.

Fighter jets and drones conducted a total of seven airstrikes in Syria Friday and Saturday, Central Command said. Jordan, Saudi Arabia and the United Arab Emirates participated in the strikes with the U.S. Air Force and the U.S. Navy.

ISIS' assault on the Syrian Kurdish town of Kobani has sent more than 100,000 refugees streaming across the border into Turkey in recent days as Kurdish forces from Iraq and Turkey have raced to the front lines to defend the town.

CBS News national security correspondent David Martin reports that the strike near Kobani was intended to take some of the pressure off of the town.

Below is video from U.S. Central Command of the strike near Kobani.

Central Command said an ISIS building and two armed vehicles at the Kobani border crossing were destroyed.

Nawaf Khalil, a spokesman for Syria's Kurdish Democratic Union Party, or PYD, said the strikes near Kobani, also known as Ayn Arab, destroyed two tanks. He said the jihadi fighters later shelled the town, wounding a number of civilians.

The strikes also destroyed an ISIS vehicle south of Al-Hasakah in eastern Syria and several buildings near Al-Hasakah that were part of an ISIS garrison, Central Command said. The strikes also damaged an ISIS command and control facility near Manbij in Syria's north.
