— Mobilized by calls on Facebook, thousands of Arab protesters marched on Israel’s borders with Syria, Lebanon and Gaza on Sunday in an unprecedented wave of demonstrations, sparking clashes that left at least 15 people dead in an annual Palestinian mourning ritual marking the anniversary of Israel’s birth.
In a surprising turn of events, hundreds of Palestinians and supporters poured across the Syrian frontier and staged riots, drawing Israeli accusations that Damascus, and its ally Iran, orchestrated the unrest to shift attention from an uprising back home. It was a rare incursion from the usually tightly controlled Syrian side and could upset the delicate balance between the two longtime foes.
