JAPAN UNDERSTANDS U.S. ATTACK ON IRAN OIL PLATFORM Japan said it understood why the U.S. Attacked an Iranian oil platform on Monday. "Japan, deeply concerned over the increasing threat to the ships navigating in the Gulf, understands the circumstances that have led the United States government to take these measures," the Foreign Ministry said in a statement. The statement added that the threat to free and safe navigation had increased after the missile attack on a U.S.-flagged tanker in Kuwaiti territorial waters last Friday.
