The Japanese reported that NRA soldiers had "run amok", causing mass destruction and a massacre of Japanese civilians, and the British Acting Consul-General reported that he had seen the bodies of Japanese males that had been castrated.[27][15] In an incident that would provoke Chinese outrage, Japanese soldiers entered a building that the Chinese later said was their negotiation headquarters, and killed Chinese diplomat Cai Gongshi, eight members of his staff, seven NRA soldiers, and one cook.[28] The exact nature of the killing is contested between the Japanese and Chinese sides, with the Japanese claiming they were attacked from the upper floors, and did not know that the building was a government office or that Cai held the position of negotiator.[29] The Chinese, on the other hand, said that the building was clearly marked, and that Cai's nose, ears, and tongue were cut off, and his eyes gouged out, before he was executed.
