This is MORNING EDITION, from NPR News. I'm Renee Montagne.
STEVE INSKEEP, HOST:
And I'm Steve Inskeep, on a tense day across the Arab world. We're gathering information from Yemen, where hundreds of protestors today breached the wall of the U.S. embassy. Witnesses say they burned an American flag, though it appears none reached the main embassy building. One reporter describes a man in the streets shouting against Jews and Christians, and the reporter adds: This is not the Yemen I know.
And the attacks in Libya and elsewhere in the Arab world come in the midst of a presidential campaign. It became, in effect, a test of leadership for both the president and his Republican challenger. NPR's Ari Shapiro reports.
ARI SHAPIRO, BYLINE: President Obama learned Wednesday morning that Ambassador Chris Stevens and three other diplomats were killed in the Libyan city of Benghazi. When he spoke in the White House Rose Garden hours later, he didn't mention politics.
