Federal prosecutors seized a container ship that had carried 35,000 pounds of cocaine into U.S. waters. The drugs, which were confiscated during a raid of the ship last month , are valued at around $1.3 billion.

The MSC Gayane was seized on July 4 after U.S. Customs and Border Protection obtained a search warrant for the massive vessel, which is roughly the length of three football fields, federal authorities said Monday.

This is momentous work by the CBP team at the Port of Philadelphia, said Casey Durst, CBPs director of field operations in Baltimore. Their vigilance and inspectional scrutiny resulted in the interception of the largest seizure of cocaine in the 230-year history of U.S. Customs and Border Protection.
