American Embassies Become Targets of Muslim Mobs

The scene turned violent after Friday prayers today and angry protesters attacked US outposts from the Middle East and Africa to Afghanistan and Pakistan, apparently inflamed by the crude insults to their religion in the video, The Innocence of Muslims. In Yemen, the American embassy was breached by an unarmed mob reportedly allowed in by local security forces; US Marines have been sent to the scene. Do the attacks result from the "Arab Spring?" Are US facilities adequately protected against a new wave of anti-Americanism?
