The double suicide bombing at the Iranian embassy in Beirut on Tuesday morning was anything but a surprise. In fact, it was almost expected given the battles in Syria between radical Sunni forces, on the one hand and Hezbollah and Iranian Revolutionary Guards forces on the other, along with the threats by al-Qaeda groups in Syria to hit Iranian targets in the area.
Nonetheless, the bombings raise the confrontation between Sunnis and Shiites in Lebanon and Syria to new heights. Two suicide bombers acting in coordination, bent on harming as many Shiites as possible, may be an almost routine phenomenon in Iraq, but in Lebanon it represents an unprecedented escalation in hostilities.

In similar fashion to the methods used by Hezbollah and the Revolutionary Guards against Western targets in Lebanon in the early 1980s, Tuesday’s assailants — who apparently belong to an al-Qaeda offshoot — sent two bombers in a coordinated attack: The first rode his motorbike to the embassy gate and blew himself up, opening the path for the second, who drove an explosives-laden car. The result was devastating: 23 fatalities and almost 150 injured.
