The release of the anti-Islamic short film Innocence of Muslims triggered numerous demonstrations across North Africa, the Middle East and South Asia.[20] On September 11, 2012, dozens of protestors scaled the walls and entered the courtyard of the U.S. embassy in Cairo, Egypt.[21][22] On September 13, 2012, protests occurred at the U.S. embassy in Sana'a, Yemen, resulting in the deaths of four protesters and injuries to thirty-five protesters and guards. On September 14, the U.S. consulate in Chennai was attacked, resulting in injuries to twenty-five protesters.[13] Protesters in Tunis, Tunisia, climbed the U.S. embassy walls and set trees on fire. At least four people were killed and forty-six injured during protests in Tunis on September 15.[5] Further protests were held at U.S. diplomatic missions and other locations in the days following the initial attacks. Related protests and attacks resulted in numerous deaths and injuries across the Middle East, Africa, Pakistan, and Afghanistan.
The 2012 Benghazi attack occurred during the night after protesters penetrated the grounds of the U.S. embassy in Cairo. For days after the attack, CIA analysts believed the Benghazi incident had been “spontaneously inspired” by the Cairo incident, which Benghazi residents could view on an Egyptian satellite television service, though analysts later concluded the attack had been planned in advance. On the day after the attack, Ansar al-Sharia claimed partial responsibility, though it also said "it was a spontaneous popular uprising in response to what happened by the West." The early conflicting accounts generated significant political controversy during subsequent investigations through 2015.[23][24][25][26]
