FSA_rebels_cleaning_their_AK47sWhen the Syrian uprising turned into a civil war in 2011, most of the trouble stayed inside Syria’s borders, but that’s changing. This week armored personnel carriers rushed to  Beirut, Lebanon, to prevent fighting between supporters and opponents of Syrian President Bashar al Assad. It’s a sign the war has spread well beyond Syria’s borders. Another sign: at an election rally last Sunday, Turkish Prime Minister Tayyip Erdogan praised the Turkish air force for shooting down a Syrian plane after it violated Turkey’s air space. “If you violate our border, our slap will be hard. Therefore, I congratulate firstly our chief of general staff, and our pilots,” Erdogan said. Also last week, Israeli warplanes struck Syrian military posts in the Golan Heights after a roadside bombing wounded four Israeli soldiers. It was some of the worst fighting on Israel’s border with Syria in decades. Israel doesn’t want a war with Syria, and Prime Minister Benjamin Netanyahu’s government has tried to steer clear of the fight between Assad and his opposition. But the conflict is expanding anyway. “I think we can already consider now that the Israeli-Syria border is back, is a conflict border once again,” Middle East expert Jonathan Spyer, with the Gloria Institute, said.
