Federal Interior Minister Mohsin Naqvi called on Iranian Foreign Minister Abbas Araghchi to discuss bilateral relations and the evolving regional situation, reported 24NewsHD TV Channel.
The meetings focused on Pakistan-Iran cooperation, regional peace efforts, and developments following the recent US-Iran agreement.
Earlier, Interior Minister Mohsin Naqvi arrived in Iran on Saturday after planned talks between Iran and the United States in Switzerland were postponed, Iranian media reported.
Tehran and Washington were due to hold talks in Switzerland on Friday, after signing a memorandum of understanding ending the war in the Middle East, but the latest negotiations have been postponed with no new date announced.
Iranian media including Tasnim news agency said Interior Minister Mohsin Naqvi landed on Saturday in the northeastern city of Mashhad.
Foreign ministry spokesman Esmaeil Baqaei had earlier told ISNA news agency that "Pakistan's interior minister will arrive in Iran at noon today, Saturday, as part of Pakistan's efforts regarding the Iran-US negotiations."
Naqvi is expected to meet his Iranian counterpart Eskandar Momeni, as well as Foreign Minister Abbas Araghchi for talks during the visit, according to Baqaei.
Quoting sources, Iranian news agency reported that Mohsin Naqvi will hold talks on the next phase of the US-Iran talks.
The interior minister will also congratulate the Iranian leadership for signing Islamabad Memorandum of Understanding (MoU) with the US.
IRNA said Mohsin Naqvi will discuss the progress of negotiations between Iran and the United States during his visit, without providing further details.
Mohsin Naqvi had visited Tehran multiple times in the context of Pakistan’s diplomatic efforts aimed at easing regional tensions and promoting dialogue. His latest visit is also being viewed as significant in terms of regional diplomacy and ongoing developments in the region.
Pakistan has been a key mediator between Tehran and Washington, with Qatar also joining the efforts in the run-up to the deal announced this week.
The war began on February 28 with US-Israeli strikes that killed supreme leader Ayatollah Ali Khamenei and several senior military commanders.
Iran retaliated with missile and drone strikes that drew in countries across in the region, before an April truce halted the worst of the fighting.
Iran on Thursday announced it signed a deal with the United States to end the hostilities, with the aim of holding further negotiations on a broader deal that would include Iran's long contested nuclear programme.
