The Kremlin said on Monday that shoulder-launched missiles obtained and used by rebels in Syria were a huge danger to all governments amid a report that Moscow ordered its warplanes in Syria to fly higher to avoid being shot down. Russias Defense Ministry has said that an aircraft, a SU-25, was downed in Syrias Idlib Province on Saturday and its pilot killed on the ground after he ejected. Speaking to reporters on a conference call, Kremlin spokesman Dmitry Peskov said on Monday it was too early to say who had supplied the weapons system which rebels had used to shoot down the plane, but that it was extremely worrying that such rockets were falling into the hands of "terrorists." The Izvestia daily said a decision had been taken that such planes would in future only fly above a ceiling of 5,000 meters in an effort to keep them safe. It said that such a policy had previously been in force, but that the SU-25s had for some reason started flying at lower altitudes in recent days.
