Isis ‘declares state of emergency in Raqqa’ according to US military

US military officials are monitoring reports that Isis have declared a state of emergency in Raqqa.

Social media and news reports that suggest Isis may have come under siege in its self-declared capital in Syria are being closely watched by the US-led anti-Isis coalition.

Col. Steve Warren, spokesman for the coalition said: “We have seen this declaration of emergency in Raqqa, whatever that means.”
