Attack at the Islamic Center of San Diego
On Monday, May 18 2026, two teenagers entered the Islamic Center of San Diego—a mosque and elementary school serving about 140 children—and opened fire. Guard Amin Abdullah exchanged gunfire, radioed a lockdown, and was killed. Storekeeper Mansour Kaziha and community member Nadir Awad were also slain; the shooters, Caleb Vazquez (18) and Cain Clark (17), died by self-inflicted wounds in a nearby vehicle.
Rising Religious Hate and the Perpetrators’ Ideology
San Diego’s hate crimes rose 150 % from 2024-2025, prompting the Islamic Center to add armed security in 2023 after neo-Nazi flyers. Court records show Vazquez was placed on a gun-violence restraining order in 2025 for “idolizing Nazis.” Both teens met in online forums and exchanged a 75-page manifesto praising the Christchurch attack and espousing white-supremacist, anti-Muslim, antisemitic and anti-LGBTQ rhetoric.
The Three Community Heroes
Amin Abdullah, a 51-year-old security guard and father of eight, greeted visitors with “Salam wa rahamatullahi.” Mansour Kaziha, 78, ran the mosque’s store and was known as “Abu Ezz.” Nadir Awad, 57, owned a limousine company and his wife taught kindergarten at the school. All three diverted the shooters and saved dozens of children.
Official Responses and Community Criticism
Police Chief Scott Wahl called Abdullah’s actions “heroic” and confirmed a hate-crime investigation. Mayor Todd Gloria said violence, hate, antisemitism and Islamophobia have no place in San Diego. CAIR California’s Hussam Ayloush warned that no community is immune to hate-motivated violence. CAIR San Diego’s Tazeen Nizam complained that meeting requests with city officials were ignored.
On-the-Ground Accounts
College freshman Sarah Youssef said the guard’s presence once comforted her but later signaled danger. Mother Nawal A-Nouri received a WhatsApp alert and described the shock of hearing gunfire “just blocks away.” Hundreds gathered at Lindbergh Park for a vigil, chanting “God is the greatest.”
Data, Gaps and Statistics
Three adults were killed; no children were injured among the 140 on site. Law enforcement seized more than 30 firearms, ammunition and a crossbow from three residences. CAIR recorded 8,683 hate-crime complaints nationwide in 2025, a historic high. The FBI has not disclosed the original owners of the weapons, and investigators have not confirmed whether the manifesto’s target list was ever completed.
