Consultations involving the heads of diplomatic missions from Pakistan, Egypt, Türkiye, and Saudi Arabia have begun in Islamabad, according to CNN.
The parties are focusing on de-escalation in the Middle East, as well as security issues.
According to the report, Pakistan — which maintains contacts with both Tehran and Washington — is playing a key mediating role, having previously shared a 15-point US peace plan with Iran.
However, analysts remain skeptical about the prospects for a swift breakthrough.
