TOKYO (AP) — Japan marked the 69th anniversary of the atomic bombing of Hiroshima on Wednesday, as Mayor Kazumi Matsui called on U.S. President Barack Obama and other world leaders to visit the city to see the scars of the atomic bombing first hand.

In his “peace declaration” speech, Matsui invited world leaders to his once-devastated hometown, referring to a proposal made at a ministerial meeting in April of the Non-Proliferation and Disarmament Initiative in Hiroshima, urging them to visit Hiroshima and Nagasaki.
