CENTRAL ISLIP, N.Y. (AP) — U.S. Attorney General Jeff Sessions will appear this week in a section of Long Island that's been plagued by deadly gang violence.

The Justice Department says Sessions will speak on violent crime, gangs and MS-13 during an appearance in Central Islip (EYE'-slihp) on Friday.

Authorities suspect MS-13 members are behind the killings of four young people on Long Island earlier this month. They're among 11 killings that have rattled working-class immigrants in the area since last year.

Last week the Trump administration announced a crackdown on MS-13.

The street gang, also called Mara Salvatrucha, was founded in Los Angeles in the mid-1980s by immigrants fleeing El Salvador's civil war.
