“At least 19 Japanese websites, including those of a government ministry, courts and a hospital, have come under cyber attack, apparently from China, police said Wednesday.
Many of the websites were altered to show messages proclaiming Chinese sovereignty over the Diaoyu islands, a Japanese-administered chain Tokyo calls Senkaku, the National Police Agency (NPA) said in a statement.”
