U.S. Democratic presidential front-runner Hillary Clinton on Tuesday outlined how she would stop homegrown terrorist attacks such as the San Bernardino, California, massacre.

Clinton said the United States should expect more terrorist attacks and must enlist the help of Silicon Valley entrepreneurs to help identify potentially radicalized individuals on social media platforms. The married couple who shot 14 people to death in the San Bernardino rampage earlier this month have been described by authorities as self-radicalized.

Clinton also called for a broader target for airstrikes in Syria; more in-depth visa application reviews for all individuals who have spent time in areas where Islamic State is active; and again called for tighter gun-control laws, including reinstating a ban on the sale of assault weapons.
