IS militants claim to have captured the Jahar Gas Field in Syria, making it the second gas field they have seized this week, according to reports on social media.
It is believed that IS are able to generate funds of around $2mn per day from the oilfields and refineries already within their control. The capture of two gas fields in a week could further boost that income.
The report said that IS fighters had seized two tanks, seven four-wheel drive cars and several heavy machine guns from defeated Syrian Army officials.
A U.S.-led coalition has conducted air strikes against Islamic State since September. The United States says it is not coordinating with Syrian President Bashar al-Assad’s forces to combat the Islamist group.
