The resulting explosion killed both Hussein brothers and their bodyguard, and reduced much of the safehouse to rubble. At 1:21 PM, several American soldiers entered the ruined house to search for survivors. As the team advanced up the stairs to the building's second floor, Qusay's 14-year-old son Mustapha, taking cover in a bedroom,[5] opened fire on the soldiers with an AK-47, but was killed instantly by return fire.[2]
