HIROSHIMA -- The city of Hiroshima on Sunday marked the 54th anniversary of the dropping of the atomic bomb by calling on the leaders of the world's nuclear states to exercise strong will in abolishing nuclear weapons.

Before a crowd estimated at 50,000, Hiroshima Mayor Tadatoshi Akiba stressed that strong will is born from the truth that nuclear weapons "are the absolute evil and will be the cause of humankind's extinction."
