Two teenage suspects fatally shot three people outside a mosque in San Diego, California, in what authorities believe may be a hate crime, before taking their own lives, police said on Monday.
The attack unfolded at the Islamic Center of San Diego, prompting a large emergency response and lockdowns at nearby schools.
San Diego Police Chief Scott Wahl said officers responding to the scene found three victims with gunshot wounds outside the mosque. Shortly afterwards, the suspects — aged 17 and 18 — were discovered dead inside a vehicle a few blocks away from self-inflicted gunshot wounds.

“It’s fair to say the security guard’s actions were heroic,” Wahl said, adding that the guard likely prevented the incident from becoming “much worse”.

California Governor Gavin Newsom said he was “horrified” by the attack, adding that the state “will not tolerate acts of terror or intimidation against communities of faith”.
US President Donald Trump called it a “terrible situation” and said authorities would examine the case closely.
The attack comes just days before Eid al-Adha, one of the most significant festivals in Islam.
Imam Taha Hassane, director of the Islamic Center, condemned the violence, saying: “This is a house of worship, not a battlefield.” The incident has heightened concerns over safety at religious sites and potential hate-driven violence in the US.
