We turn now to Washington for more reaction to this brazen attack. The Obama administration is sending a Marine anti-terrorism unit to bolster security in Libya. It's also taking precautions elsewhere. The stepped up security comes as the State Department mourns its losses. NPR's Michele Kelemen has that story.
MICHELE KELEMEN, BYLINE: Shock and sadness hovered over the State Department as Secretary of State Hillary Clinton spoke of the devastating losses of four foreign service personnel.
This morning, Secretary of State Hillary Clinton said this about the slain ambassador, Christopher Stevens.
SECRETARY HILLARY CLINTON: He risked his life to stop a tyrant, then gave his life trying to help build a better Libya. The world needs more Chris Stevenses.
BLOCK: Earlier this year, before Chris Stevens assumed his position as ambassador to Libya, he made a video, subtitled in Arabic, directed to the Libyan people. It was posted on the U.S. Embassy's website and on YouTube.

In this hour of the program, we remember Christopher Stevens, the first sitting U.S. ambassador killed in more than 30 years. And we'll explore how the attacks in Libya and Egypt have become fodder for political debate.
The eurozone crisis has weighed heavily on the global economy and it will remain a central foreign-policy challenge for President Obama or Mitt Romney, whichever man wins in November. The Obama administration has repeatedly urged eurozone countries to shift their focus from austerity to growth. This week, we're focusing on foreign policy issues facing the next administration.
And NPR's Sylvia Poggioli has this story on the eurozone.
