Obama to visit Hiroshima but no apology
President Barack Obama is to make a historically symbolic visit to Hiroshima later this month.
No serving US president has visited the Japanese city since it was hit by a US nuclear bomb during World War Two.
The bombing in 1945 killed 140,000 people and, along with a second bombing on Nagasaki, is credited with ending the war.
The White House has made it clear there will be no apology for the bombing.
The BBC's Gary O'Donoghue reports.
