US president Barack Obama today won the strongest backing yet from Russia on the Iranian nuclear crisis as he warned that Tehran was "running out of time".
Russian president Dmitry Medvedev said after talks with Obama that neither he nor the US leader were satisfied with the pace of progress, as Tehran drags its feet over its response to a UN-sponsored nuclear enrichment deal.
Obama described as "fair" the proposal, which would see states including Russia help the Islamic republic enrich uranium.
"Unfortunately, so far at least, Iran has been unable to say yes," he said. "We now are running out of time with respect to that approach."
Russia has the strongest ties with Iran of any major power, and its capacity to provide technical help for the Iranian nuclear drive is seen by some analysts as giving it unmatched leverage in Tehran.
Medvedev said that Moscow was "not completely happy about the pace" of efforts aimed at defusing the stand-off with Iran.
"Our goal is clear, it is transparent," he said. "We are prepared to work further" to ensure Iran's nuclear programme is only for peaceful purposes, he said.
