Russian President Vladimir Putin's threat to use nuclear weapons in the war against Ukraine has opened the eyes of a Ukrainian woman living in Hiroshima to the horrors of nuclear warfare, pushing her to take a stand in solidarity with her compatriots.

In March, a group of Ukrainians staged a protest against the Russian invasion in front of the Atomic Bomb Dome, the skeletal remains of a building preserved as a memorial after the August 1945 atomic bombing of the city.

The protest drew about 120 Ukrainians and Japanese living in Hiroshima Prefecture. They chanted "Stop the war," and held up signs reading "STOP PUTIN" over the blue-and-yellow Ukrainian flag.
