He stood outside the rubble of an apartment building that was struck and destroyed by what the police said was a Katyusha rocket. “They were defiant about what happened. Even people who didn’t want to vote before, they went after this rocket.”

Iraqis, he went on, “are not afraid of bombs anymore.”…

“These are the messengers of Iraq’s enemies, the enemies of democracy,” said Ammar al-Hakim, a leader of a Shiite coalition, the Iraqi National Alliance, that hopes to deny Mr. Maliki a second term. “It is a desperate and weak message.”
