A Russian MiG-31 fighter jet has been scrambled to escort a US B-1B strategic bomber over the Sea of Japan, TASS news agency reported on Sunday citing the Russian military, just days after an incident with a US naval destroyer in the same region.
It said the bomber had not breached the Russian border.
Russia said on Friday one of its military vessels chased away a US destroyer that attempted to violate Russian territorial waters during Russian-Chinese naval drills in the Sea of Japan, something Washington said was false.
