epa04336676 A picture made available on 31 July 2014, shows smoke rising from the Baiji oil refinery during the clashes between the fighters of jihadist Islamic State in Iraq and the Levant (ISIL) and Iraqi forces in Baiji city, northern Iraq, on 30 July 2014. The UN Security Council expressed ‘grave concern’ over reports that radical militant groups the Islamic State and Jabhat al-Nusra have seized oil fields in Iraq and Syria and called on all states to refrain from engaging in oil trade with them. The council said both the Islamic State, formerly known as ISIL, and Jabhat al-Nusra, an al-Qaeda affiliate also known as al-Nusra Front, are listed as terrorist groups and engaging in oil sales with them would mean providing financial support to them.
