The US should consider a possible no fly zone against DAESH in northern Syria, John Allen, the US special presidential envoy for the global coalition against DAESH in Iraq and Syria told CNN on Thursday.
"We should consider all the measures," Allen said, adding, "We should consider them, whether we would ultimately adopt them or not."
He stated, "I have to tell you we have looked at this: that the intricacies and the complexities and the cost, frankly, in terms of additional resources, of a no-fly zone or a safe zone, are not insignificant."
Although President Barack Obama has not agreed yet to the proposal, Turkey has consistently defended a plan to establish safe areas and no-fly-zones in northern Syria to protect displaced civilians.
The Turkish Foreign Ministry previously said that refugees who stay in Turkey and neighbouring countries could be settled in the “safe” areas which would be cleared of DAESH by Turkey and US-led coalition forces with operations against the group.
In early September, Turkish Prime Minister Ahmet Davutoglu said his government has vigorously tried to persuade world leaders to establish a safe zone in northern Syria in order to help relocate refugees and displaced people back into the country.
