A YouTube trailer of Sam Bacile's movie, that is being deemed offensive to Islam, set off angry assaults on US missions in Egypt and Libya.
The US consulate in Benghazi was set on fire yesterday reportedly killing one American consular official.
Later, an angry mob armed with rockets and guns stormed the American consulate in Benghazi last night resulting in the death of US ambassador to Libya Christopher Stevens and three members of his staff.
Bacile was apologetic about the American consular official who was killed but he blamed lax embassy security and the perpetrators of the violence.
