The mayors of Hiroshima and Nagasaki have requested that U.S. President Donald Trump visit the atomic-bombed cities this year to commemorate the 80th anniversary of the attacks and the end of World War II.

“We hope that you will listen to the voices of civil society, visit the atomic-bombed cities, listen to the firsthand accounts of the hibakusha and fully grasp the inhumanity of nuclear weapons and accept the hibakusha’s earnest desire for peace,” Hiroshima Mayor Kazumi Matsui and Nagasaki Mayor Shiro Suzuki wrote in a letter addressed to the new U.S. president Tuesday.

Both mayors reportedly visited the U.S. Embassy in Tokyo the same day to present the letter to Charge d'Affaires ad interim Katherine Monahan, who took over for Ambassador Rahm Emanuel, who left his post earlier this month.
