A memorial service was held Friday in Hiroshima to mourn Korean victims of the U.S. atomic bombing there 71 years ago, including those who had been forcibly brought to Japan from the Korean Peninsula before and during World War II.

The Korean Peninsula was under Japan's colonial rule from 1910 to 1945.

The annual ceremony took place in front of a monument at the Hiroshima Peace Memorial Park, with some 300 participants attending, including atomic bomb survivors and officials of the South Korean consulate general in Hiroshima.
