In a phone conversation to Russian President Vladimir Putin on Tuesday afternoon. Prime Minister Binyamin Netanyahu expressed regret for the deaths of 15 crew members in the plane shot down Monday night. He told Putin that Syria was responsible for shooting down the Russian aircraft. It was important to continue the security coordination between the two armies in Syria, which had saved many losses on both sides, he said. Netanyahu proposed sending the Israeli Air Force commander to Moscow with all the relevant information needed for the Russian investigation of the incident. Before the phone call, Putin attributed the loss of the Il-20 reconnaissance plan to a “chain of tragic circumstances.” He also vowed to substantially boost security for the Russian troops posted in Syria.
