Questions continue to cloud Tuesday’s attack at the U.S. Consulate in Libya, where four Americans including ambassador Chris Stevens were killed. The motives of the attack by allegedly a pro-al Qaeda military group are unclear, but some are pinning the attacks as a violent reaction to an obscure American-made film demeaning the prophet Mohammed. President Barack Obama said in a public statement that the U.S. “will not waver in our commitment to see that justice is done for this terrible act – and make no mistake, justice will be done.” Meanwhile, violent protests have spread outside the U.S. embassies in Egypt and Yemen.
