A suicide bomb attack at a recruitment center for the Iraqi army on Wednesday killed at least six people and wounded 20, police said. The attacker, with explosives hidden beneath his clothes, set them off while standing among the job applicants in Tal Afar, 150 kilometers (93 miles) east of the Syrian border and 420 kilometers (260 miles) northwest of Baghdad, The Associated Press quoted police Brig. Saeed Ahmed Al-Jibori as saying.
