BAGHDAD — A suicide bomber killed 13 Iraqi army recruits and wounded more than 30 in Baghdad on Thursday, police said, in an attack on men responding to a government appeal for volunteers to help fight Al-Qaeda-linked militants in Anbar province. Police said a man with an explosive vest had blown himself up as recruits were registering their names at the small Muthanna airfield, now used by the army in the Iraqi capital. No group immediately claimed responsibility for the attack, which occurred a day after Prime Minister Nouri Al-Maliki vowed to eradicate Al-Qaeda in Iraq. – AFP
