In response to a question, Prince Saud Al-Faisal denied that he and the German senior foreign policy official expressed "upset" of the work against ISIL, saying that we, instead, confirmed that the work should go within clear strategy and goals using great capabilities that make effect on the ground. He added that collective work against ISIL is a must as the group threatens Iraq and comfortably using the Syrian territory as a safe haven. The German minister stated that the airstrikes have so far hindered the progress of ISIL in Iraq, despite confusing reports yesterday from Syria that the strikes could be launched in much complicated circumstances, citing ISIL fighters infiltrating inside densely-populated and residential areas, making it difficult for the airstrikes to be strictly pinpointed. For his part, Prince Saud Al-Faisal called for the unification of Syrian rebels into the Free Army of Syria to keep their country united as they are not working for revenge but for the honor and dignity of their people regardless of their identity or sect. --More 23:13 LOCAL TIME 20:13 GMT www.spa.gov.sa/w
