Japan says Russia war plane violates air space

TOKYO/MOSCOW (Reuters) - Japan protested to Moscow after a Russian military plane violated Japanese air space over the Izu Islands on Saturday, a Japanese Foreign Ministry official said.

The Foreign Ministry told Moscow to investigate the case and sought an explanation, the official said.

The Russian warplane flew over the isle of Sofugan, about 650 km south of Tokyo, around 7:30 a.m. (2230 GMT on Friday), the official said.

"We strongly protest against the violation," the official said.

Russia said four turbo-prop TU-95 "Bear" strategic bombers went on a routine 10-hour mission over the Pacific and were accompanied by Japanese and U.S. war planes.

"All flights of the Russian Air Force were carried out in accordance with international air space regulations without breaching the other states' borders," Air Force spokesman Alexander Drobyshevsky told Interfax news agency.

The TU-95, Russia's longest serving bomber, is capable of carrying AS-15 "Kent" cruise missiles which can deliver a nuclear warhead. The air force did not say if the aircraft involved were carrying live weapons.

Russia last violated Japanese air space in January 2006, when a Russian plane flew over Rebun Island off the coast of Hokkaido, a major island in the north, the Japanese official said.

Kyodo news agency reported that 22 Japanese fighter jets were scrambled to deal with the intrusion.
