Authorities say the three people killed by two teen shooters at a San Diego mosque died while saving roughly 140 children who were in the building at the time of the attack. San Diego's police chief says all three men were shot while trying to delay and distract the two gunmen who barged into the Islamic Center of San Diego on Monday. The victims have been identified as Amin Abdullah, Nadir Awad, and Mansour Kaziha. Authorities say security guard Abdullah confronted the shooters and warned everyone of danger. Police say Awad and Kaziha later drew the gunmen out of the building.
