Hayashi said they "run counter to Japan's position on the Northern Territories and are unacceptable," and that Tokyo lodged its protest with Moscow via diplomatic channels on both occasions. The first warning on Oct. 5 said a live-fire drill will be held in a period until Nov. 1 in waters off one of the islands, he said. The second received Monday was for the temporary suspension of the innocent passage of foreign military and government vessels in waters around the Northern Territories until next Monday. The right to innocent passage under the U.N. Convention on the Law of the Sea ensures that a foreign ship can sail through the territorial waters of another state unless it poses a security threat.
