NAGASAKI, Japan (Kyodo) -- Nagasaki marked the 76th anniversary Monday of the U.S. atomic bombing of the city in World War II, with its mayor urging the Japanese government to take a more active role in realizing a world free of nuclear weapons.
At the annual memorial ceremony, Mayor Tomihisa Taue urged the government to sign and ratify a U.N. treaty banning nuclear weapons and join as an observer in its first meeting of state parties to the treaty, which came into effect in January, and explore building a nuclear-weapon-free zone in northeast Asia.
