New York Gov. Andrew Cuomo said the state will provide expanded access to intelligence and law enforcement resources in an effort help federal and local authorities crack down on the recent spate of deadly gang violence on Long Island.

The Democratic governor on Wednesday announced that State Police will also launch expanded patrols and undercover operations in the Brentwood and Central Islip areas of Suffolk County.

"This concerted law enforcement effort now, combining federal, state, and local resources, we believe is going to make a marked difference and as I say, we will not rest until MS-13 is put out of business because we have zero tolerance in this state for the thuggery that MS-13 has made their calling card," Cuomo said.

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

U.S. Attorney General Jeff Sessions plans to visit the area on Friday.

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