US-led coalition planes pounded oil sites in Syria Sunday that fund the Islamic State group, as Syria's Al-Qaeda branch warned that people in Europe and America will pay the price. The United States, along with coalition partners Saudi Arabia and the United Arab Emirates, targeted four modular refineries and an IS command and control post, all north of Raqa in Syria, US Central Command said.
"Initial indications are that they (the strikes) were successful," it said. In his first speech since air raids were launched on Syria this week, the head of the Al-Qaeda affiliate there, Al-Nusra Front, warned of reprisals.
"Your leaders will not pay the price for the war alone, you will pay the higher price," Abu Mohammad al-Jolani said in an Internet audio message, addressing "people of America and Europe".
Failure to stop these air strikes "will transfer the battle to your very homes", he said.
Washington has said it would press on with "near continuous" strikes, and the latest raids were part of intensifying efforts to disrupt the group's lucrative oil-pumping and smuggling operations. The jihadists control a swathe of territory straddling north-western Iraq and eastern Syria, home to most of Syria's main oilfields, and their oil infrastructure is the main target of the air strikes.
Experts say the jihadists were earning as much as $3 million (2.4 million euros) daily from oil before the coalition began launching strikes on Syria, building on the air war under way against IS in Iraq since August 8.
Sunday's strikes hit close to the Turkish frontier, near Tal Abyad, said the Syrian Observatory for Human Rights, destroying "at least three makeshift refineries under IS control". "IS had been refining crude and selling it to Turkish buyers," said the Britain-based monitor, which relies on a network of sources inside Syria.
Coalition warplanes hit the jihadist heartland province of Raqa early Sunday and the raids destroyed a plastics factory outside Raqa city, killing one civilian, the Observatory said.
The coalition strikes also destroyed a tank and damaged another near Deir Ezzor in eastern Syria, US Central Command said.
The Pentagon said US-led air strikes in Iraq near insurgent-held Fallujah on Sunday destroyed two IS checkpoints and a transport vehicle.
On the ground in western Iraq, pro-government forces backed by warplanes on Sunday repelled an IS attack on the strategic town of Amriyat al-Fallujah, security sources said. "Warplanes eventually engaged the insurgents and killed 15 of them," local police chief Aref al-Janabi said, without identifying the aircraft.
The town "has strategic importance. It is a main logistics road for the army and it is the link between Anbar and Karbala", a Shia holy city south of Baghdad, Janabi said.
Several European governments have approved plans to join the air campaign in Iraq, including most recently Britain, and Turkish President Recep Tayyip Erdogan said on Sunday Ankara "cannot stay" out of the fight.
British warplanes flew their first combat mission over Iraq on Saturday but returned to base in Cyprus with their bombs after no targets were identified.
"They are flying daily over the area where the fighting is and they are ready as part of the international force to be called in by the ground troops if they can help directly with some of the fighting," British Defence Secretary Michael Fallon said.
