Interior Minister Mohsin Naqvi arrived in Mashhad on Saturday for high-level meetings aimed at advancing diplomatic efforts following the recent Iran-US memorandum of understanding (MoU).

Iran’s IRNA  and Fars news agencies reported that he would visit the Imam Reza Shrine and hold meetings before leaving for Tehran.

Iranian Foreign Ministry Spokesperson Esmaeil Baghaei told ISNA that Naqvi’s visit was part of Pakistan’s continued mediation efforts to bridge remaining differences between Tehran and Washington and preserve the momentum generated by the recently announced understanding.

During the visit, Naqvi is expected to hold separate meetings with Iranian Interior Minister Eskandar Momeni and Foreign Minister Abbas Araghchi to discuss the next phase of diplomatic engagement.

The visit came as the preliminary Iran-US agreement entered a critical stage, with both sides preparing for technical negotiations covering the nuclear programme, sanctions relief and mechanisms for verifying mutual commitments.

According to Iranian officials, Pakistan had played a significant behind-the-scenes role in facilitating dialogue between Tehran and Washington over recent months, helping ease tensions that ultimately led to the war-ending memorandum of understanding.

Diplomatic sources cited by ISNA described the upcoming negotiations as particularly sensitive, with both sides expected to address complex political and technical issues before any final, legally binding agreement can be reached.

Islamabad’s latest diplomatic push is intended to help prevent setbacks during the negotiations and maintain progress achieved through months of mediation, the ISNA report said.
