There’s a new front. Israeli warplanes on Saturday reportedly killed six Syrian and allied soldiers what an Israeli general called the “most significant attack” inside Syria since 1982. Israel said an Iranian drone first penetrated its airspace, prompting a retaliatory strike that ended with Syrian fire hitting an F-16, which crashed in northern Israel after its pilots bailed out. A wave of Israeli airstrikes against Iranian targets and Syrian antiaircraft batteries followed. Russian President Vladimir Putin, whose forces back the Syrian regime, urged restraint, which analysts believe is in all sides’ best interest.
