San Diego mosque attack

Two teenage attackers opened fire at the Islamic Center of San Diego in California on Monday, killing three people and prompting police to treat the incident as a hate crime.

San Diego Police Chief Scott Wahl said at a press conference, "It's fair to say his actions were heroic. No doubt he saved many lives today."

Authorities said the police first received a report of the attack at 11:43 local time, 18:43 GMT, and "spotted three bodies of victims outside the building."

The Islamic Center campus includes Rashid School, which offers religious and language courses, and children were in classrooms when the incident occurred.

FBI: online radicalization

The FBI said the two teenagers who shot and killed three people in the attack met online and shared white supremacist views, with Mark Remily saying, "They didn't discriminate on who they hated."

AP reported that investigators found at least 30 guns, ammunition and a crossbow at two residences after Monday's attack, and that the shooters, Cain Clark, 17, and Caleb Vazquez, 18, killed themselves, according to police.

Imam Taha Hassane said Abdullah engaged the suspects in a gunbattle and called for a lockdown on his radio, adding, "He “sacrificed his life to stop them from getting inside the classrooms.""

NBC News reported that the suspects’ writings were being authenticated and that Mark Remily said, "They didn’t discriminate on who they hated," while NBC also described the document as filled with neo-Nazi ideology and racist meme culture.

Community impact and next steps

After the attack, community leaders and faith figures praised the three men killed for slowing the attackers, and NPR quoted Ghouse Mohammed saying, "All three of them were heroes."

NPR also reported that Mark Remily said, "We are thoroughly investigating this case to learn everything we can and will not stop until we get to the bottom of what happened and why," while the FBI urged the public to provide information that could assist the investigation.

The Washington Post reported that Amin Abdullah was so disturbed by the 2019 massacre at mosques in Christchurch, New Zealand that he became a security guard, and it quoted imam Taha Hassane saying, "If he didn’t do what he did, and he sacrificed his life, the two suspects could have easily accessed every single classroom."

CNN reported that authorities were reviewing a live video and a lengthy 75-page document filled with racist, anti Islam and anti Semitic ideologies, and that the attackers posted a live video of the incident before killing themselves.
