US and Iran step back from nuclear talks

Prospects for negotiations between the United States and Iran on nuclear proliferation have dimmed significantly.Just a few days ago, it seemed the two sides were ready to return to negotiations. But US President Donald Trump then said he was not speaking to Iran and was not offering Tehran anything. Iran's deputy foreign minister has told the BBC his country won't enter into talks on its nuclear programme. Also in the programme: We'll get a rare glimpse at life inside the Ukrainian city of Mariupol after three years of Russian occupation; and after calling the shots for 148 years, tennis tournament Wimbledon says goodbye to human line judges.(Photo: Iran's deputy foreign minister Majid Takht-Ravanchi in an interview with the BBC's Lyse Doucet.
