A small explosion damaged a public toilet on the grounds of a contentious Japanese war shine on Monday, drawing police bomb squad technicians and firefighters to the scene and prompting the shrine to close some areas to visitors, the Japanese news media reported. There were no reports of injuries at the shrine, Yasukuni, which has long been the focus of political tensions. It honors Japanese leaders convicted of war crimes by Allied tribunals after World War II, along with millions of common soldiers and sailors killed in that conflict and others since the 19th century.
