PHILADELPHIA (AP) — U.S. authorities say they have seized more than $1 billion worth of cocaine from a ship at Philadelphia’s port, calling it one of the largest drug busts in American history. The U.S. attorney’s office in Philadelphia announced the massive bust on Twitter on Tuesday afternoon. Officials said agents seized about 33,000 pounds of cocaine from a large ship at the Packer Marine Terminal. Authorities say two members of the ship’s crew have been arrested and charged.
