The U.S. government is crushing more than a ton of confiscated illegal ivory in Times Square in an effort to halt elephant poaching and ivory trafficking.

Interior Secretary Sally Jewell said Friday's event in New York would also crush "the bloody ivory market."

Hundreds of ivory trinkets were loaded onto a conveyor belt and into a rock crusher after Jewell joined officials from advocacy groups and other federal and state agencies for a news conference.

The crusher is depositing the powdered ivory into a trough to be trucked away.

Animal advocates say the trade in ivory threatens to wipe out African elephants.
