Iranian Deputy Foreign Minister Abbas Araghchi told Sputnik that the readiness of the US to station atomic bombs at the Büchel airbase in Germany is a concern for Iran, and called on all states which have such weapons of mass destruction to abide their obligations under the Non-Proliferation Treaty.
"We are undoubtedly concerned about any changes in this respect, and we hope that all states with nuclear weapons will fulfill their obligations," RIA Novosti cited him as saying.
