Russia has sent some military equipment and soldiers to its borders which it shares with North Korea.
Military vehicles and vehicles have been deployed near the Russian city of Vladivostok on the borders between North Korea and Russia.
Images broadcast by the inhabitants of that city show the passage of a Russian military convoy conformed by several military vehicles, tanks and armored ones that are used for the transport of troops.
The images also show part of the S-400 air defense system, among others, that will serve to address the possible entry of aircraft and missiles into Russian airspace.
Experts point out that recent moves on the Korean peninsula ensure that the deployment of Russian forces indicates Moscow's concern about a possible military confrontation in North Korea.
So far, there has been no comment from the Russian authorities on the deployment of troops in Vladivostok, near North Korea, which could become the scene of a war with the United States.
The Asian country had already declared itself "ready for war" with the United States and warned of the "catastrophic consequences" that would be derived from the actions of Pyongyang, if forced to defend itself against the provocations of Washington.
