Kremlin Spokesman Dmitry Peskov has not confirmed reports that Russian President Vladimir Putin accepted the proposal to help mediate nuclear weapons talks between the US and Iran.

"No, I can’t confirm it," he told reporters in response to a question on the subject.

Bloomberg earlier reported, citing sources, that US President Donald Trump asked Russian President Vladimir Putin during their February phone call to mediate in talks with Iran over that country's nuclear program, and the Russian side agreed.
