Deir Ezzor siege lifting is important, but terrorism won’t be defeated in Syria only by the military operations, UN chief said.

“It will be an important factor, but I have no illusions that we will not eliminate terrorism just by these military operations. To eliminate terrorism, we also need to address several of its root causes and so a political solution is also a very important instrument,” claimed Guterres.

Last week  most of Deir Ezzor was liberated by SAA with its allies.
