DUBAI: Iran has agreed to hold a fourth round of nuclear talks with the United States on Sunday in Oman, Foreign Minister Abbas Aragchi said on Friday, adding that the negotiations were advancing.

US President Donald Trump, who withdrew Washington from a 2015 deal between Tehran and world powers meant to curb its nuclear activity, has threatened to bomb Iran if no new deal is reached to resolve the long unresolved dispute.

Western countries say Iran鈥檚 nuclear program, which Tehran accelerated after the US walkout from the now moribund 2015 accord, is geared toward producing weapons, whereas Iran insists it is purely for civilian purposes.

鈥淭he negotiations are moving forward, and naturally, the further we go, the more consultations and reviews are needed,鈥� Aragchi said in remarks carried by Iranian state media.

鈥淭he delegations require more time to examine the issues that are raised. But what is important is that we are on a forward-moving path and gradually entering into the details.鈥�

The fourth round of indirect negotiations, initially scheduled for May 3 in Rome, was postponed, with mediator Oman citing 鈥渓ogistical reasons.鈥�

Aragchi said a planned visit to Qatar and 萝莉视频 on Saturday was in line with 鈥渃ontinuous consultations鈥� with neighboring countries to 鈥渁ddress their concerns and mutual interests鈥� about the nuclear issue.
