MNA � Secretary of Supreme National Security Council has not ruled out possibility that Russian fighter jets could use Iranian airspace to hit targets in Syrian territories against extremists.

Mr. Ali Shamkhani�told reporters that Iran and Russia had promoted their relations to strategic levels especially on Syria; �Iran and Russia cooperate in Syria not in single case, but the coordination is comprehensive, embracing different aspects; accordingly, Iran�s airspace welcomes Russian fighter jets in case they seek hitting terrorists� targets in Syria,� he added, believing that security officials could consider the case as possible.

However, Shamkhani also said that the issuing permissions would require a relatively complex process where different organizations and regulating bodies could engage to address the two principles of timing and the necessity of the flights over Iranian airspace.
