San Diego mosque gunmen left chilling manifesto and live-streamed attack

San Diego police reveal heroic actions of Islamic Center shooting victims

Two teenagers who shot and killed three men during a shooting incident in a San Diego mosque in California were radicalized through online platforms where they initially connected and exchanged white supremacist ideologies, as per authorities and their own writings.

The 17- and 18-year-old assailants took their own lives shortly after Monday's shooting.

This came a day after friends and family identified Amin Abdullah as the security guard who was killed while trying to prevent suspected attackers from entering the mosque complex.
