On the anniversary of 9/11, America found itself questioning yet another horrific tragedy with deaths of Chris Stevens, the U.S. ambassador to Libya, and three other Americans.
The four were killed Tuesday – caught in a storm of gunfire and flames -- when a group of armed men stormed the U.S. consulate in Benghazi.
Both President Barack Obama and Secretary of State Hillary Clinton denounced the attack as ruthless act of violence.
"This is an attack that should attack the conscious of people of all faiths around the world," Clinton said. "We condemn in the strongest terms, this senseless acts of violence."
Obama vowed that retribution will be sought.
"I can't imagine that Chris Stevens died in Benghazi, because it is a city that he helped to save," said Obama.
While a terrorist group affiliated with Al Qaeda claims responsibility for the well-coordinated attack, U.S. security officials are still trying to determine whether it was deliberately timed with the 11th anniversary of 9/11.
