President Barack Obama took no questions Wednesday at a White House press conference on the attacks in Libya in which U.S. ambassador Chris Stevens as well as three other Americans were killed, walking away as a reporter asked, "Is this an act of war?" Obama, flanked by Secretary of State Hillary Clinton, said: "The United States condemns in the strongest terms this outrageous and shocking attack. We're working with the government of Libya to secure our diplomats. I've also directed my administration to increase our security at diplomatic posts around the world. And make no mistake -- we will work with the Libyan government to bring to justice the killers who attacked our people. ... Since our founding, the United States has been a nation that accepts all faiths. We reject all efforts to denigrate the religious beliefs of others. But there is absolutely no justification to this type of senseless violence -- none. The world must stand together to unequivocally reject these brutal acts. Many Libyans have joined us in doing so." He added that "this attack will not break the bonds between the United States and Libya."
