WASHINGTON - Barack Obama will become the first sitting US president to visit atomic bomb-struck Hiroshima during a trip to Japan later this month, the White House said Tuesday.
Obama, accompanied by Prime Minister Shinzo Abe, will make the deeply symbolic visit on May 27, after attending a G7 summit in southern Japan, said spokesman Josh Earnest.
The White House described the trip as an effort to highlight the US "commitment to pursuing the peace and security of a world without nuclear weapons." Obama will visit the once ruined city's Peace Memorial Park "where he will share his reflections on the significance of the site and the events that occurred there," said senior Obama foreign policy advisor Ben Rhodes.
The announcement comes after months of speculation in the US and Japan that the president, a Nobel peace laureate, would make a visit to the city devastated in the final days of World War II.
On August 6, 1945, the US dropped the world's first atomic bomb on Hiroshima, killing around 140,000 people, including those who survived the explosion itself but died soon after from severe radiation exposure.
Three days later, the US military dropped a plutonium bomb on the port city of Nagasaki, killing some 74,000 people.
The bombings remain controversial in the United States and across the world, with opinion sharply divided on whether their use ended the brutality of the war and avoided a US invasion of Japan, or whether dropping atomic weapons on civilians constitutes a war crime.
Last month, Secretary of State John Kerry became the highest ranking US political figure to visit Hiroshima.
He said he was "deeply moved" by the experience and a "gut-wrenching display that tugs at all your sensibilities as a human being.
"Everyone should visit Hiroshima, and everyone means everyone," he added, fueling speculation that Obama would go.
Japan has long urged world leaders to visit Hiroshima and Nagasaki to see the horrors of the atomic bombings and join efforts to eradicate nuclear arms.
But some have been concerned that Obama's visit would be seen as an apology for events of seven decades ago.
A presidential visit could also rile Obama's opponents and some in the military whose predecessors carried out presidential orders to drop the bombs.
The visit would come at a particularly sensitive time. This December marks the 75th anniversary of Japan's attack on Pearl Harbor, in Obama's home state of Hawaii.
But the White House was eager to stress that Obama's visit is not an apology.
"He will not revisit the decision to use the atomic bomb at the end of World War II. Instead, he will offer a forward-looking vision focused on our shared future," said Rhodes.
The visit is likely to have regional reverberations, at a time when North Korea, a short distance away, is aggressively pursuing its nuclear and ballistic missiles development programme.
At a four-day Communist Party confab that ended on Monday, Pyongyang's enigmatic leaders vowed to continue building weapons systems that have already prompted deep international sanctions, opprobrium and isolation.
Japan's neighbours in China and South Korea will also be watching the visit closely, always eager to make sure that their once hyper-aggressive foe is not allowed to play the role of a World War II victim.
Before his visit to Japan, Obama will head to Vietnam for talks on advancing co-operation on trade, security and human rights, the White House said.
Obama will deliver a speech on US-Vietnam relations in Hanoi and also visit Ho Chi Minh City.
