Top Iranian and U.S. negotiators began a new round of indirect talks on Saturday to hammer out a deal curbing Tehran's nuclear programme, while U.S. President Donald Trump signalled confidence in clinching a new pact that would block Iran's path to a nuclear bomb.

Iran and the US plan to continue their negotiations on the Iranian nuclear programme in the coming week, Iranian Foreign Minister Abbas Araghchi said this after the third round of negotiations in Oman on Saturday.
