In Iraq, the U.S. effort to push out Prime Minister Ibrahim al-Jaafari is gaining momentum. Last week the U.S. Ambassador to Iraq Zalmay Khalilzad notified Shiite politicians that President Bush no longer supported Jaafari and wanted a new leader. Over the weekend one of Iraq’s leading Shiite political blocks joined the growing call for Jaafari to resign. On Sunday, Secretary of State Condoleezza Rice and British foreign minister Jack Straw made a surprise visit to Baghdad and urged Iraqi leaders to form a new government. Meanwhile a group of prominent Shiite clerics are now calling for the expulsion of US ambassador Zalmay Khalilzad from Iraq. They accuse him of being anti-Shiite.
