Iran's chief nuclear negotiator called for a global nuclear weapons ban on Monday but insisted all nations - including his own - have a right to develop nuclear energy.
Visiting Tokyo to meet with senior Japanese officials, Saeed Jalili insisted that his country's nuclear program is for civilian purposes, although the US and other nations fear its goal is to produce weapons.
"The crime that was committed in Hiroshima must never be repeated," Jalili told reporters at the Foreign Correspondents' Club of Japan, referring to the United States' dropping of an atomic bomb on Hiroshima, Japan, at the end of World War II. "A global determination must be made to disarm all nations with these weapons."
US President Barack Obama's administration has given a rough deadline of year-end for Iran to respond to an offer of engagement and show that it would allay world concerns about its nuclear program.
