Pakistan's army chief, Field Marshal Asim Munir, is due to visit Tehran on Tuesday, according to a Pakistani official and Iranian media cited by Reuters.
Reuters reported the visit on Monday. The Pakistani official was not named. Reuters said Pakistan "has played a key mediating role between the U.S. and Iran this year".
Tasnim news agency, described as affiliated with Iran's Islamic Revolutionary Guard Corps, reported on Monday that he would visit on Tuesday, according to an Iran International live blog.
Arab News Pakistan, citing Tasnim, said Field Marshal Munir would travel to discuss regional developments. It said Pakistan's mediation role would also be discussed.
Reuters said the visit follows summer talks with Iranian leaders on preventing escalation, reopening the Strait of Hormuz and ending the conflict quickly.
Fox News, citing Reuters and Iranian state media, said the talks would focus on the same issues. It also reported on 19 October that Iran had warned the US and Israel against renewing attacks.
No official Pakistani statement on the visit had been reported. Pakistan's military media wing, the Inter-Services Public Relations (ISPR), had not been reported as commenting. No statement from the Iranian government had been reported either.
It was not clear whom Field Marshal Munir would meet. His formal titles are Chief of Army Staff and Chief of Defence Forces.
Pakistani outlets Daily Pakistan and Pakistan Observer, citing Iranian media including ISNA, described the visit as likely rather than confirmed. Reuters and Tasnim said he was due to travel or would travel.
Pakistan Observer and Daily Pakistan described the diplomacy as stalled and the US-Iran confrontation as escalating. They cited disputes over sanctions relief, security commitments and maritime access.
Pakistan is a neighbour of Iran and a channel to Washington. According to Pakistan Observer, Iran's Foreign Ministry and others have praised its mediation.
The US and Israel have been at war with Iran this year, according to Al Jazeera. It said Pakistan has been the main mediator.
The Islamabad Talks in April 2026 were the first direct US-Iran negotiations in more than four decades, Al Jazeera said. They ended without a breakthrough.
Field Marshal Munir visited Tehran in April, on 22 and 23 May, and on 24 August. In May he met Iran's Foreign Minister Abbas Araghchi, according to Press TV, Iran International and ETV Bharat.
In August he met Iranian President Masoud Pezeshkian and Mr Araghchi, according to Pakistan's military, as reported by Bloomberg. Pakistan's Interior Minister Mohsin Naqvi accompanied him.
Al Jazeera reported that Tehran, not Islamabad, announced the August visit. Iranian Foreign Ministry spokesperson Esmaeil Baghaei said that trip would build on Pakistan's efforts to "help strengthen peace and security in the region".
Mr Araghchi met Field Marshal Munir in Rawalpindi on 24 April, according to Al Jazeera. A Reuters photo caption shows a US-Iran-Pakistan-Qatar meeting at Bürgenstock, Switzerland, on 21 June 2026.
Iran International, an opposition outlet, said his mediation led to the Memorandum of Islamabad in June. That claim came from a single source.
Before the August trip, Field Marshal Munir spoke to US President Donald Trump, according to three Pakistani sources cited by Reuters. The US was then threatening sanctions on Iran and its trade partners.
Statements from the ISPR and Iran's Foreign Ministry on the visit may follow. None had been reported.
