Authorities identify three victims in the San Diego mosque shooting and describe their roles during the attack. According to reporting from Al Jazeera and Al-Monitor, the victims are Amin Abdullah, Mansour Kaziha, and Nader Awad.

Both outlets also state that the victims’ actions were connected to the response during the incident, indicating they were involved as the attack unfolded rather than as bystanders. The coverage focuses on confirming the names of those who died and outlining how each person’s conduct related to efforts to stop or limit the attack. The sources do not conflict on the number of victims identified in this reporting and agree on the three names.
