A newly discovered U.S. military document from 1948 shows that American authorities at the time recognized the Dokdo islets as a part of Korean territory, a local research foundation said Tuesday. The classified report, compiled by the U.S. Far East Air Forces (FEAF) on June 24, 1948, states that it had been "definitely established in September 1947 that the Liancourt Rocks was a part of Korea," using the Western name for Korea's easternmost islets of Dokdo. The document, titled "Report of Bombing of Liancourt Rocks," reported on an incident earlier that month in which U.S. Air Force aircraft conducting a training exercise bombed the islets, killing 14 Korean fishermen and injuring several others. Dokdo has long been a recurring source of tension between Korea and Japan, as Tokyo has continued to make territorial claims over the islets in its policy papers, public statements and school textbooks. Korea maintains a small police detachment on the islets, effectively controlling them. The report's wording is seen as effectively acknowledging Dokdo as Korean territory, according to the North
