The FBI says most of the arrests were made Thursday morning throughout New York City, in New Jersey and New England. Charges include murder, extortion and narcotics trafficking.

More than 100 suspected mobsters are charged and more than 90 were rounded up in pre-dawn FBI raids, CBS News' Pat Milton reports.

It includes the five La Cosa Nostra families in New York, the de Cavalzante crime family in New Jersey and two alleged mob members of New England organized crime families.

The charges cover four murders and labor racketeering involving the International Longshoremen.

Attorney General Eric Holder and other officials were expected to discuss the cases later Thursday at a news conference in Brooklyn.

The takedown was another blow to New York's five Mafia crime families. Federal probes aided by mob turncoats have decimated the families' ranks and resulted in lengthy prison terms for several leaders.

The acting boss of the Colombo crime family and one of the ruling members of the Gambino crime family were among those arrested, sources said.
