Russia has relocated 1,500 people from a city that sits along the border with North Korea after Kim Jong Un launched a missile over Japan that landed in the northern Pacific Ocean early Tuesday, U.K.'s Daily Star reported.
Russian President Vladimir Putin ordered citizens to leave Vladivostok and relocate to "safe areas" in the country's far east because of increasing tensions in the region.
The surprise move comes after President Donald Trump warned "all options are on the table" in terms of a U.S. response to the missile launch. Trump said North Korea has "signaled its contempt for its neighbors, for all members of the United Nations, and for minimum standards of acceptable international behavior."
The Daily Star said Putin is concerned the United States will wage war against North Korea should it fire more missiles.
The U.N. has placed sanctions on North Korea over nuclear and ballistic missile testing, but that has not stopped Kim as his country's nuclear capabilities have sharply increased. Putin has had a "treaty of friendship, good-neighborliness, and cooperation" with North Korea since he first assumed power in 2000.
