LONDON — Londoners are learning about the plight of 2,000 orphans "ignored" by authorities following the atomic bombing of Hiroshima 65 years ago.

Shozo Kawamoto, 76, has visited various venues in the British capital in the runup to Friday's anniversary to educate more people about the "hidden victims" of the atomic bombing, which initially and in the ensuring months claimed some 140,000 lives.

Kawamoto, also promoting London's first exhibition on the atomic attacks on Hiroshima and Nagasaki, on Tuesday told members of the British pressure group Campaign for Nuclear Disarmament that about 1,000 children who lost their parents in the bombing were left to "starve to death" in the aftermath of the attack.
