Iraq will host another round of talks between regional foes Iran and Saudi Arabia on Wednesday, the foreign ministry in Baghdad said on Saturday, without giving further details. The Iraqi foreign minister, Fuad Hussein, revealed the development during remarks at a diplomatic forum in Antalya on Turkey’s southern coast cited by local media. A foreign ministry spokesperson confirmed the comments to Reuters. The talks will be the fourth round hosted by Baghdad between officials from its two neighbours and mutual adversaries, according to local media. The Saudi foreign ministry did not respond to a request for comment. Diplomats hope the opening of direct channels between Iran and Saudi Arabia will signal an easing of tensions across the Middle East after years of hostilities that have brought the region close to a full-scale conflict. Talks to revive the 2015 Iran nuclear deal on Friday faced the prospect of collapse after a last-minute Russian demand forced world powers to pause negotiations for an undetermined time despite having a largely completed text. Negotiators have reached the final stages of 11 months of discussions to restore the deal, which lifted sanctions on Iran in return for curbs on its nuclear programme, long seen by the west as a cover for developing atomic bombs.
