Chief of Army Staff and Chief of Defence Forces Field Marshal Asim Munir and Interior Minister Mohsin Naqvi, along with Pakistani delegation, have arrived in Tehran as part of the ongoing mediation efforts to end US-Iran war, the Inter-Services Public Relations said in a statement on Wednesday.

The high-level delegation is visiting Tehran as Pakistan steps up efforts to turn the two-week ceasefire into a lasting peace, with source saying a second round of talks between the two sides is likely to be held in Islamabad by the end of next week.

Officials and security agencies have been instructed to make necessary administrative and security arrangements ahead of the talks, sources said.

According to sources, the US delegation for the talks will include US Vice President JD Vance, special envoy Steve Witkoff, and US President Donald Trump’s son-in-law Jared Kushner.

The Iranian delegation will comprise Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, they said.

The development comes just days after the same delegations held talks in Islamabad to finalise an agreement to end the war in the Middle East.

The conflict began on February 28, when the US and Israel launched a joint bombing campaign against Iran. The scope quickly expanded as Iran effectively blocked the Strait of Hormuz and launched attacks against Israel and US bases in the Middle East.

Hostilities between the US and Iran ended on April 8 when Prime Minister Shehbaz Sharif announced a two-week ceasefire between the two sides. He also invited delegations from both countries to the federal capital to settle their dispute.

However, the talks, which ran for around 21 hours, could not result in an agreement as Tehran and Washington disagreed on key issues such as Iran’s nuclear and ballistic missile programme, the Strait of Hormuz and the removal of US sanctions on Iran.

Despite the talks ending without an agreement, PM Shehbaz said that Islamabad was making all-out efforts to resolve pending issues between the US and Iran.

A spokesperson for Iran’s foreign ministry confirmed the same today, saying Tehran and Washington were exchanging messages via Pakistan.

In a media briefing, Iranian Foreign Ministry spokesperson Esmaeil Baqaei said that multiple messages have been exchanged following the first phase of a ceasefire.

He added that it was highly likely that Tehran would host a Pakistani delegation today (Wednesday) as part of the negotiations process.

The Pakistani delegation, he said, will arrive in the country to relay messages from the US in continuation of the Islamabad Talks.

Baqaei noted that the previous talks held in Islamabad included discussions on a complete ceasefire, lifting of sanctions, and compensation for damages incurred during the war.

The issue of restoring Iran’s frozen assets was also raised, though no outcome was achieved, he said.

He said that any future negotiations would focus on securing a full ceasefire, adding that reports regarding an extension in the ongoing truce were unconfirmed.

A senior US official also said that Washington has also not formally agreed to the extension of its ceasefire with Iran.

“There is continued engagement between the US and Iran to reach a deal,” a senior US official told Reuters.
