An Iraqi military spokesman, Brig. Qassim al-Moussawi, called the suicide bombing an inside job, telling state television that an al-Qaida fighter had infiltrated al-Zubaie’s security detachment. Al-Moussawi offered no details, and repeated calls to his office to verify the claim went unanswered. The Interior Ministry, which oversees Iraq’s police forces, said it had no information on that claim. Al-Maliki aide Mariam Taleb al-Rayes also told al-Sharqiyah television the attacker had “infiltrated” al-Zubaie’s inner circle, but did not elaborate. BAGHDAD – Striking at the Iraqi government’s highest-ranking Sunni Arab, a suicide bomber blew himself up among worshippers at the deputy prime minister’s home Friday, seriously wounding the leader and killing at least nine people in a security breakdown that shook the image of a calming Baghdad. Salam Al-Zubaie underwent surgery to remove shrapnel from his abdomen at a U.S.-run hospital. Prime Minister Nouri al-Maliki, head of the Shiite Muslim-dominated government, said his deputy was in serious but stable condition. The bombing, coming just a day after a Katyusha rocket slammed to earth 50 yards from visiting U.N. Secretary-General Ban Ki-moon, starkly emphasized the continuing chaos in Iraq even after the introduction of thousands more American soldiers and six weeks of an extensive security crackdown in the capital. Growing U.S. voter disenchantment with the war, now in its fifth year, prompted a narrowly divided House of Representatives to vote Friday to order the withdrawal of combat troops next year in Congress’ boldest challenge to Bush administration policy. President George W. Bush said he would veto the measure if it passed the Senate and reached his desk. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
