Obama: "No justification" for Libya attack

In Washington, a day after after the the U.S. ambassador and three other diplomats were killed in Libya.

SOUNDBITE: U.S. President Barack Obama saying:

"Make no mistake, justice will be done. We will work with the Libyan government to bring to justice the killers who attacked our people."

The U.S. is dispatching additional forces to shore up security at its embassies worldwide. The attack on the consulate in Libya --- on the eleventh anniversary of September 11th --- was reportedly a response to a film insulting the Prophet Mohammad.

SOUNDBITE: U.S. President Barack Obama saying:

"We reject all efforts to denigrate the beliefs of other but there is no justification to this type of senseless violence."

The situation in Benghazi highlights a still fragile security situation in the Middle East following last year's Arab Spring. It also has some in Washington wondering if it will inspire other outbreaks of violence against U.S. installations.
