♦ A fourth round of talks between the US and Iran over Tehran’s nuclear programme concluded in the Omani capital, Muscat.

♦ The US has insisted that Iran must scrap its uranium enrichment to prevent the country from developing nuclear weapons, but Tehran denies it has any such aim and again stressed it does not intend to give up the programme.

♦ Donald Trump pulled out of a previous nuclear agreement between Iran and five other world powers in 2018.

♦ Two previous rounds of the negotiations were held in Muscat, with one taking place in the Omani embassy in Rome.
