Colombia's navy says it has seized a shipment of 2.6 metric tons (2.9 tons) of cocaine aboard a boat off the country's Pacific coast.

Officials said the drug shipment was seized Monday in a joint operation with the U.S. Coast Guard.

Capt. Jorge Tovar says the bust occurred about 70 miles (110 kilometers) off the Colombian state of Choco. He said it was the largest seizure in the past four years in the area.

He said on Tuesday that four people were captured and that the cocaine had been bound for Central America.

Navy Vice Adm. Hernando Wills said that on Monday authorities also found $650,000 in apparent drug money aboard another boat that seemed to be returning to Colombia from Central America. He said one person was arrested.
