The Okinawa Defense Bureau and the city of Okinawa uncovered seven more barrels Tuesday at a former U.S. military installation in the prefecture that may have been used to hold toxic chemicals during the Vietnam War, stoking concern among residents.
Prior to Tuesday¡¯s findings, the city had dug up 19 barrels from the same site in mid-June.
The barrels found Tuesday had been buried about 1 meter deep in a soccer ground adjacent to the Kadena Air Base that had been part of the installation until 1987, the Defense Ministry said.
