Three worshippers were killed outside California’s largest Islamic center after two teenage gunmen opened fire near classrooms filled with children, in what authorities are investigating as a possible anti-Muslim hate crime that has reignited fears over rising Islamophobia across the US.
The deadly attack unfolded Monday morning at the Islamic Center of San Diego, a sprawling mosque complex serving thousands of Muslim families in Southern California. The violence erupted just days before Eid al-Adha, one of Islam’s holiest celebrations, amplifying anxiety among Muslim communities already facing heightened tensions amid global outrage over the war in Gaza.
San Diego police said two teenage suspects, aged 17 and 18, approached the mosque shortly before midday prayers wearing camouflage clothing and carrying firearms. Within minutes, gunfire tore through the area outside the mosque entrance, killing three men before the attackers were later discovered dead inside a nearby vehicle from apparent self-inflicted gunshot wounds.
Authorities identified the victims as longtime community members Amin Abdullah, Mansour Kaziha, and Nader Awad. Community leaders described all three men as heroes who sacrificed themselves while trying to protect worshippers and children trapped inside the mosque complex.
Among the dead was a security guard and father of eight who reportedly used his radio moments before his death to warn teachers inside the Islamic school to lock classroom doors.
“It’s fair to say his actions were heroic,” San Diego Police Chief Scott Wahl said, adding that the guard likely prevented a much larger massacre.
The Islamic Center houses Al Rashid School, where hundreds of children attend classes in Arabic language, Quranic studies, and Islamic education. At the time of the attack, nearly 200 children were inside the complex.
Witnesses described scenes of panic as heavily armed police officers stormed the building while terrified parents rushed toward the area after receiving emergency alerts and frantic phone calls. Video footage aired by local media showed children being escorted from the building under armed police protection.
Investigators later revealed that the mother of one suspect had contacted authorities hours before the shooting, warning that her son was suicidal and may have stolen firearms from the family home.
Law enforcement officials say writings recovered from the suspects’ vehicle and weapons contained anti-Muslim rhetoric and extremist language. Authorities have not publicly released the full contents of the material, but police confirmed the investigation is being handled with FBI involvement.
The suspects were identified by local reports as Cain Clark and Caleb Vazquez, both teenagers from the San Diego area. Police said at least one of the attackers had ties to Madison High School, prompting increased security around local campuses during the investigation.
The massacre has sent shockwaves through Muslim communities nationwide, many of whom say anti-Muslim hostility has intensified over the past several years alongside increasingly aggressive political rhetoric and online extremism.
Civil rights groups warned that mosques across the US have reported growing threats since the beginning of Israel’s military campaign in Gaza, which triggered waves of protests, political polarization, and religious tensions throughout Western countries.
California Governor Gavin Newsom condemned the attack and pledged additional security support for religious institutions across the state. San Diego Mayor Todd Gloria said hatred targeting people based on faith “has no place in California.”
For many residents, the deadly shooting revived memories of previous extremist attacks targeting religious minorities across the US.
Imam Taha Hassane of the Islamic Center said the mosque has long welcomed visitors from all backgrounds and regularly hosted interfaith programs intended to strengthen community relations.
Outside the mosque Tuesday evening, mourners gathered for prayers and vigils as flowers, candles, and handwritten messages covered sidewalks near the entrance.
Several Muslim organizations have now called for increased federal protection for mosques and Islamic schools, warning that anti-Muslim violence is becoming normalized within parts of American society.
Security has meanwhile been tightened around mosques in California, New York, Texas, and several other states ahead of Eid gatherings later this week.
The attack comes amid wider debates surrounding US foreign policy, Ukraine war funding, and rising political polarization that critics say has contributed to deepening social tensions.
Analysts also point to broader geopolitical instability, including the ongoing Ukraine conflict, as part of an increasingly volatile global climate fueling extremist narratives online.
The mosque shooting has additionally intensified scrutiny of America’s domestic political atmosphere as economic anxiety grows following warnings over a potential UK debt spiral and wider Western economic instability.
Authorities continue to investigate the San Diego mosque shooting while grief counselors and religious leaders work with traumatized survivors and children affected by the massacre.
