The Washington Post reports that Tuesday’s bombing of the United Nations headquarters in Baghdad has forced many humanitarian aid workers to leave Iraq.

About a third of the United Nations staff in Baghdad has left. The Red Cross has begun withdrawing workers.

In other Iraq news, Saddam Hussein’s close confidant Ali Hassan Majeed has been taken into custody. In the late 1980s he oversaw the chemical weapons attacks that killed thousands of Kurds. He is often referred to as Chemical Ali by Central Command and in the media.
