The two teenage assailants responsible for a mass shooting at the Islamic Center of San Diego, California, rushed toward the mosque “fully armored” with handguns and rifles, authorities said. A security guard shot and struck one of the shooters, according to members of the mosque, but the attacker continued charging. The guard, Amin Abdullah, alerted administrators of the school at the Islamic Center, telling them to go into lockdown, before he was shot and killed.
