War crimes: As part of the Briggs Plan devised by British General Sir Harold Briggs, 500,000 people (roughly ten percent of Malaya's population) were eventually removed from the land and interned in guarded camps called "New Villages". The intent of this measure was to isolate villagers from contact with insurgents. While considered necessary, some of the cases involving the widespread destruction went beyond justification of military necessity. This practice was prohibited by the Geneva Conventions and customary international law which stated that the destruction of property must not happen unless rendered absolutely necessary by military operations. 1950–1953: Korean War United States perpetrated crimes North Korean perpetrated crimes Rudolph Rummel estimated that the North Korean Army executed at least 500,000 civilians during the Korean War with many dying in North Korea's drive to conscript South Koreans to their war effort. Throughout the conflict, North Korean and Chinese forces routinely mistreated U.S. and UN prisoners of war. Mass starvation and diseases swept through the Chinese-run POW camps during the winter of 1950–51. About 43 percent of all U.S. POWs died during this period. In violation of the Geneva Conventions which explicitly stated that captor states must repatriate prisoners of war to their homeland as quickly as possible, North Korea detained South Korean POWs for decades after the ceasefire. Over 88,000 South Korean soldiers were missing and the Communists' themselves had claimed they had captured 70,000 South Koreans. South Korean perpetrated crimes 1952–1960: Mau Mau uprising In attempt to suppress the insurgency in Kenya, British colonial authorities suspended civil liberties within the country. In response to the rebellion, many Kikuyu were relocated. According to British authorities 80,000 were interned. Caroline Elkins estimated that between 160,000 and 320,000 were moved into concentration camps. Other estimates are as high as 450,000 interned. Most of the remainder – more than a million – were held in "enclosed villages". Although some were Mau Mau guerillas, many were victims of collective punishment that colonial authorities imposed on large areas of the country. Thousands suffered beatings and sexual assaults during "screenings" intended to extract information about the Mau Mau threat. Later, prisoners suffered even worse mistreatment in an attempt to force them to renounce their allegiance to the insurgency and to obey commands. Significant numbers were murdered; official accounts describe some prisoners being roasted alive. Prisoners were questioned with the help of "slicing off ears, boring holes in eardrums,
