On 17 September 2018, the Israeli Air Force (IAF) conducted missile strikes against multiple targets in government-controlled western Syria. Syrian air defences responded to the Israeli fighter jets, accidentally shooting a Russian military Il-20, killing 15 crew aboard.[6] Russia blamed Israel for the loss of its plane, accusing the IAF of "hiding behind the Russian aircraft", thereby putting it in the line of fire.[7] The Israel Defense Forces accepted responsibility for the airstrikes the following day, but expressed sorrow regarding the loss of a Russian plane.[8][9] The strikes occurred a few hours after a Russo-Turkish agreement to create a demilitarized zone around Idlib Governorate was achieved, which postponed an imminent offensive operation by Syria's forces and its allies.[10]
