A suicide bomber attacked Iraqis applying for jobs as policemen Tuesday, killing nine and wounding 21. The suicide attack occurred in Baqouba, 50 kilometers (30 miles) north of Baghdad, where the Iraqis were submitting applications to join Iraq's Quick Reaction Police Force, said the police commander, who spoke on condition of anonymity because of concerns about his security. The blast, set off by explosives hidden under the insurgent's clothing, occurred inside a police building where the applications were being filled out and accepted, the Associated Press quoted the commander as saying. Adhid Mita'ab, an official in Baqouba General Hospital, where the casualties were rushed, said nine Iraqis were killed and 21 wounded. The commander confirmed those figures. That raised to at least 61 the number of people killed in the past three days in Iraq, less than a month before a national referendum on Iraq's draft constitution. --MORE 1113 Local Time 0813 GMT
