Honolulu Mayor Peter Carlisle marked the 66th anniversary of the bombing of Hiroshima, Japan with residents of that city.
Carlisle, along with wife Judy, laid a wreath Saturday at the annual Hiroshima Peace Memorial Ceremony in Hiroshima. He is the second U.S. mayor to travel to that ceremony.
Carlisle made the visit as part of an ongoing effort to strengthen Honolulu’s ties to Japanese cities.
On Aug. 6, 1945 the United States dropped an atomic bomb on the city of Hiroshima, leading to Japan’s surrender and the end of World War II.
Another commemoration was held in Honolulu on Friday. That event featured bombing survivors, religious leaders and members of a little league baseball team from Japan.
