Hue Uses Ground-Penetrating Radar to Locate Suspected Mass Graves

The Steering Committee for the Search, Recovery, and Identification of Fallen Soldiers' Remains in Hue on the afternoon of June 26 announced that an initial ground-penetrating radar survey at two suspected mass grave sites within the Hue Imperial Citadel had identified three areas of disturbed geological formations. The findings are considered an important scientific basis for authorities to develop excavation, search, and recovery plans for the remains of fallen soldiers in the coming period.

On June 26, the committee, in coordination with the Design Institute under the General Department of Logistics and Technical Services of the Ministry of National Defence, held a meeting to conduct a preliminary assessment of the results from the ground-penetrating radar survey at suspected mass grave sites across the city.

Earlier, on the afternoon and evening of June 25, the institute's technical team carried out radar scans at two locations: Xuan 68 Street and Ton That Thiep Street in Phu Xuan Ward, Hue City, under the direct supervision of Lieutenant General Ha Tho Binh, Commander of Military Region 4. At the survey sites, Ha Tho Binh instructed all participating forces to conduct the work with the highest level of responsibility while closely integrating radar data with information provided by witnesses, veterans, local residents, and historical records to improve the accuracy of identifying suspected mass grave locations.

According to the survey team, preliminary analysis of the radar signals identified three areas showing signs of disturbed geological formations, providing a basis for further study and verification before proceeding with the next stages of the operation.

On Xuan 68 Street, the radar system detected two suspected disturbed zones near the walls of the Hue Imperial Citadel. These areas are located at a depth of approximately 1.2 meters, with a width of about 2.5 meters and lengths ranging from 10 to 12 meters. At the intersection of Ton That Thiep Street and Thai Phien Street, adjacent to the Chanh Tay Gate of the citadel, the equipment identified another suspected disturbed area at a depth of around 1 meter and measuring between 7 and 9 meters wide. At a depth of roughly 3.5 meters, however, significant signal interference was detected, making data analysis more challenging.

Representatives of the survey team emphasized that these findings remain preliminary. In the coming period, the institute will continue processing the collected data and complete a detailed technical report for submission to the Ministry of National Defence and the Hue Steering Committee for the Search, Recovery, and Identification of Fallen Soldiers' Remains. The report will serve as the basis for considering subsequent survey and excavation activities in accordance with regulations.

Speaking at the meeting, Colonel Ha Van Ai, Deputy Political Commissar of the Hue City Military Command, highly appreciated the support provided by the Design Institute and the General Department of Logistics and Technical Services in applying ground-penetrating radar technology to the survey effort. According to Ha Van Ai, the initial results are of great significance, providing scientific evidence that will help relevant agencies formulate plans and advise competent authorities in directing the search, recovery, and identification of fallen soldiers' remains in a more systematic and effective manner.

The leadership of the Hue City Military Command also expressed hope for continued cooperation and technical support from the Design Institute in conducting more in-depth assessments of the survey results, enabling authorities to accurately identify excavation sites and help return the remains of fallen soldiers to their comrades and families.

According to the plan, ground-penetrating radar will continue to be deployed over the coming days to survey additional locations covering a total area of approximately 1,350 square meters. These sites have all been identified based on information collected from witnesses, veterans, and historical documents, with the expectation that the effort will accelerate the search, recovery, and identification of fallen soldiers' remains throughout Hue City.
