Nagasaki Mayor Tomihisa Taue on Wednesday said he handed a letter to U.S. Ambassador to Japan Caroline Kennedy during a meeting in Tokyo, urging President Barack Obama to visit the atomic-bombed city when he comes to Japan to attend the Group of Seven summit next month.

"Please express your country's steadfast determination to achieve the abolition of nuclear weapons through a message, stating that Nagasaki must be the last place to suffer the devastation they bring," the letter said.

"The people of Nagasaki ardently wish to see the realization of both your visit to Hiroshima, and of course to Nagasaki."
