Russia wants Iran to provide explanations over its nuclear programme and fully cooperate with the international community, President Dmitry Medvedev said on Thursday. In his latest tough statement on the Islamic republic's atomic drive, Medvedev warned Iran's leadership that it does not "live in space" and said Iranian leaders were using the nuclear crisis for political ends. "Iran is an active trade partner of ours. But this does not mean that we are indifferent to how Iran is developing its nuclear programme," Medvedev said at a news conference alongside German Chancellor Angela Merkel. "We are not indifferent to how the military component of this programme looks. In this respect we expect the corresponding explanations from Iran," he said.
