The leaders of Russia and Israel have made efforts to defuse tension following the downing of a Russian military plane.
The Il-20 reconnaissance aircraft, with 15 Russians on board, was downed by Syrian forces amid an Israeli air raid.
Russian President Vladimir Putin told reporters that the incident was "a chain of tragic chance events,"
Israeli Prime Minister Benjamin Netanyahu "expressed his condolences" and "promised to provide detailed information on the activities of the Israeli Air Force over Syrian territory on that day," the Kremlin said.
Euronews correspondent Galina Polonskaya said "the question is not whether Russia should go away from Syria, the question is what Russia needs to do in order to avoid such incidents in the future,"
"Military analysts explained that this so-called friendly fire is a very common thing at any war and it causes much more casualties than the fire of an enemy," Polonskaya added.
