Angry Shiite Muslims pelted Prime Minister Nouri Maliki’s motorcade with stones Sunday after the Iraqi leader pleaded for national reconciliation at a memorial held in Sadr City for victims of a large-scale bombing attack. Maliki, who is a Shiite, left the scene after he tried without success to calm a crowd of mourners calling for revenge against Sunni Arabs. His pleas were met with shouts of “coward!” and “collaborator!” … Elsewhere in the capital, the head of the Sunni bloc, Adnan Dulaimi, came under attack in the Adel neighborhood. For an hour, his guards held off armed men who had already lobbed mortar rounds toward his house but missed. Eventually, Iraqi and American forces arrived and the gunmen fled.
