BAGHDAD (Reuters) - A bomb attack on a residential building in Iraq's northern city of Mosul on Wednesday killed at least seven people and wounded more than 70, police said.
Witnesses said it was one of the biggest explosions they had ever heard in Mosul, part of a region where al Qaeda in Iraq militants have regrouped after being pushed out of Baghdad and western Anbar province.
The Sunni Islamist militant group is blamed for most major bombings in Iraq.
