A midday active shooter attack at the Islamic Center of San Diego on Monday, May 18, 2026, has left at least two people dead, including a dedicated campus security guard. A massive multi-agency response and a tactical SWAT deployment successfully neutralized the armed threat within an hour, ending a terrifying sequence that briefly forced local schools and nearby religious institutions into mandatory lockdowns.
SAN DIEGO, CA — A peaceful afternoon of prayer was shattered by violence at the largest mosque in San Diego County. At approximately 11:40 a.m. on Monday, May 18, 2026, the San Diego Police Department (SDPD) began receiving frantic 911 calls reporting multiple gunshots and an active shooter on the campus of the Islamic Center of San Diego, located at 7050 Eckstrom Avenue in the Clairemont Mesa neighborhood.

Dozens of emergency vehicles and tactical units immediately swarmed the modernist white building, which houses both the house of worship and the Al Rashid School. Authorities issued an immediate shelter-in-place order for the surrounding residential streets and shopping plazas, while the California Highway Patrol closed both the northbound and southbound Interstate 805 off-ramps at Balboa Avenue to isolate the threat.
Sacrifice at the Perimeter
While official police statements remain lean regarding the sequence of events, community leaders and activists close to the mosque confirm that two individuals have died. Tragically, one of the victims was a mosque security guard who reportedly encountered the gunman near the parking lot entrance and attempted to intercept him, absorbing the initial rounds and giving others inside the time to lock down and seek cover.
Aerial footage from local news affiliates captured a harrowing but orderly scene as tactical officers escorted more than a dozen school children, holding hands, out of the parking lot toward safety.
The Threat Neutralized
By 12:43 p.m., SDPD reported that the scene was “active but contained” as a SWAT team systematically cleared the facility. Just after 1:00 p.m., police officials delivered the definitive update that the shooter had been neutralized, meaning the immediate danger to the public had passed.
A reunification center was quickly established at 4125 Hathaway Street for family members seeking to connect with loved ones who were inside the facility or the school during the assault. Out of an abundance of caution, the Jewish Federation of San Diego and several other religious institutions throughout the city briefly enacted lockdown protocols until the suspect’s status was confirmed.
“Emergency personnel are on scene and actively working to protect the community and secure the area,” San Diego Mayor Todd Gloria said in a statement, urging residents to continue avoiding the primary thoroughfares around Balboa Avenue while detectives document the extensive crime scene.
Safety Tip: Active shooter incidents at houses of worship represent a highly specific tactical threat profile. Assailants often choose these locations because they expect a “soft target” with open doors and a welcoming environment. In this tragic event, the presence of a dedicated security guard at the perimeter was the critical factor that disrupted the shooter’s timeline and prevented an unchecked intrusion into the main prayer hall or the attached school.
