MOSCOW — Russian President Vladimir Putin sought to assuage Israel’s fears of potential Iranian and Syrian aggression, during talks with Israeli Prime Minister Benjamin Netanyahu on Monday that also addressed concerns over Russia’s military buildup in Syria. The West suspects that Russia’s movement of aircraft, missiles, tanks and other military equipment to Syria is intended to support the government of President Bashar Assad. At the start of their meeting at Putin’s residence outside Moscow, Netanyahu told him that Iran and Syria have been supplying Hezbollah with advanced weapons and are “trying to set up a second terrorist front on the Golan Heights,” which Israel captured from Syria and effectively annexed in 1981. Secretary of State John Kerry warned last week that Russia’s movement of tactical aircraft and surface-to-air missiles to Syria could pose a threat to American and allied forces fighting Islamic State. Satellite imagery also has shown the recent arrival of Russian tanks, armored personnel carriers and other military equipment at an air base near the Syrian coastal city of Latakia.
