WASHINGTON (Reuters) - Another U.S.-built facility at a naval base in Cambodia has been demolished, U.S. researchers said on Monday, citing recent satellite imagery. The Center for Strategic and International Studies (CSIS) published images showing a Rigid-Hulled Inflatable Boat maintenance facility at Cambodia’s Ream Naval Base still standing on Oct. 1 and the same site without it on Nov. 4. The news comes after the Pentagon said last month it was concerned about reports that the U.S.-funded Cambodian Navy tactical headquarters facility at Ream just south of the maintenance facility had been demolished.
