President Barack Obama challenged world leaders to speak out forcefully against what he called the politics of division and violence, and confront deeper causes of anger in the Muslim world.
During an address Tuesday at the United Nations General Assembly, Obama said attacks such as the one that killed U.S. Ambassador to Libya Chris Stevens and three other Americans are an assault not only on America but ideals the United Nations was founded on.
He began and ended his speech with a description of Stevens as someone who worked to bring democracy to Libya and build bridges between cultures. The United States, he said, will be relentless in bringing the killers to justice.
