Students and teachers attending pro-North Korean schools in Japan have received dozens of threatening phone calls and letters -- and in some cases have been physically assaulted -- since Pyongyang test-fired a barrage of missiles, a teachers federation said.
North Korea rattled Japan when it fired off seven missiles which landed in the Sea of Japan over a week ago.
Since then, schools and teachers affiliated with North Korea have reported 112 incidents of harassment, the teachers federation of North Koreans residing in Japan said in a statement issued Friday. The federation is affiliated with Chongryun, the pro-North General Association of Korean Residents in Japan.
Callers have threatened to kill students and throw Molotov cocktails at the schools, and demanded "North Koreans go home," the federation said in a statement.
Four incidents of assault have been reported to police, it said. In one case a young boy was punched in the face as he was on his way to school, and in another, a teenage boy was knocked off his bicycle by a man in his 30s, it said.
Children attending Korean schools are easily identified by their distinctive school uniform.
