A Russian MiG-31 fighter jet has been scrambled to escort a US B-1B strategic bomber over the Sea of Japan, just days after an incident with a US naval destroyer in the same region, reports Reuters on Sunday citing TASS news agency.
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.
