US authorities have lured dozens of people suspected of being involved in an international smuggling ring into custody by inviting them to a wedding.

The FBI invited the suspects to a fake wedding between two undercover agents.

"Invitations were sent out, a date was given and RSVPs were received from different points around the world," US attorney Christopher J Christie said.
