The United States has been accused of committing a "crime against humanity" when it launched twin nuclear attacks in Japan's Hiroshima and Nagasaki during World War II. A Russian government official has recently called for an international investigation and insisted the U.S. be charged for its "senseless" mass killing.

Sergey Naryshin, Russia's Lower House Speaker, said in a public speech that the twin nuclear bombings of the two cities in Japan should be investigated with lawyers and international law specialists. He described the WWII U.S. attacks as "a pure act of intimidation" that resulted in the deaths of thousands of civilians. He added that it should be regarded as a possible crime against humanity with no statute of limitation, RT News reported.

Naryshin believes the U.S. attacks on Hiroshima and Nagasaki was not justifiable based on a pure military position. He said Japan's defeat was already decided after the Soviet forces achieved victory in Manchuria.

Japanese officials and international rights groups continue to reprise the issue and spread the belief that the radioactive fallout from the U.S. bombings had affected the children of Hiroshima and Nagasaki. They claimed that the fallout has caused several illnesses resulting in the people's costly medical bills.

According to Press TV, the victims of the atomic bomb explosions had not achieved "justice" for their suffering. Following the surrender of Japan that ended WWII, historical records showed that U.S. officials held a series of trials dubbed as "Tokyo Trials." Majority of Japan's military and political leaders were subsequently executed after their indictment.

The U.S. twin atomic bombs killed between 150,000 and 250,000 people, majority of whom were civilians, according to RT. Historical reports had indicated that the U.S. officials launched the attacks to push Japan to give up the fight and prevented a combat operation on land that would have caused heavy casualties to the U.S. military.

Meanwhile, experts are have begun calling on Japan to play a greater role in the international effort toward nuclear disarmament. Joseph Cirincione, president of a U.S. group Ploughshares Fund with the aim to create a non-nuclear world, said the Japanese government should be more supportive in the global effort, Japan Times reported.

Since Japan has become an ally to the U.S., it could help President Barack Obama in pushing his nuclear disarmament agenda. Talks between Russia and the U.S. have stalled amid the ongoing tensions due to the Ukraine conflict. Arms Control Association executive director Daryl Kimball, has proposed a nuclear disarmament summit in 2015 and suggested Japan as the host country.
