On 12 April 2007, the canteen of the Council of Representatives of Iraq building was attacked by a suicide bomber, killing one to eight people and wounding 23 others. The attack, in the heavily fortified Green Zone of Baghdad, occurred ten minutes after the Council of Representatives had adjourned for lunch. It was on the first floor of the Baghdad Convention Center, which houses the parliament.[1] Two further unexploded suicide vests were found near the canteen.[1] The building had earlier been searched by dogs – very rare considering dogs are considered ritually unclean by Iraqis – suggesting the authorities suspected an attack was imminent.[2] Following the attack the government closed down mobile phone networks and Apache helicopters flew overhead.[3]
