Pakistan is gearing up to host a second round of talks between the United States (US) and Iran in Islamabad, with US advance teams arriving in the capital amidst tightened security, while Tehran has said it will not send a delegation for the dialogue.

US President Donald Trump announced that American negotiators will travel to Islamabad on Monday for possible talks aimed at ending the US-Israel war involving Iran.

“My representatives are going to Islamabad, Pakistan. They will be there tomorrow evening for negotiations,” Trump wrote on Truth Social.


He did not specify which officials would be part of the delegation. Last weekend’s talks were led by Vice President JD Vance but ended without an agreement.

Trump also accused Iran of violating the two-week ceasefire due to expire on Wednesday, alleging that Tehran opened fire in the Strait of Hormuz on Saturday.

“We’re offering a very fair and reasonable deal, and I hope they take it because, if they don’t, the United States is going to knock out every single power plant, and every single bridge, in Iran,” Trump wrote.

However, Iran rejected the second round of talks and said it would not participate under current conditions.

Iranian Foreign Ministry spokesperson Esmaeil Baghaei also confirmed that the country has decided not to send its negotiation team to Islamabad for the second round, adding that Tehran has conveyed its position to Pakistan, which is the “sole official mediator” in the ongoing diplomatic process.

He went on to say that the US violated the ceasefire agreement, pointing to the imposition of a naval blockade on Iran. “The US violated the ceasefire agreement by imposing a naval blockade on us.”

Earlier, Iran’s state news agency IRNA also reported that Tehran said its absence from the negotiations was due to Washington DC’s “excessive demands, unrealistic expectations, constant shifts in stance, repeated contradictions and the ongoing naval blockade”, which it considers a violation of the ceasefire.

Earlier, Iran’s Tasnim News Agency reported that there was no decision to send a negotiating delegation to Pakistan “as long as there is a naval blockade” on Iranian ports.

Iran’s Foreign Ministry also condemned the reported US naval blockade.

“The United States’ so-called ‘blockade’ of Iran’s ports or coastline is not only a violation of Pakistani-mediated ceasefire but also both unlawful and criminal,” Foreign Ministry spokesman Esmaeil Baghaei wrote on X.

“Moreover, by deliberately inflicting collective punishment on the Iranian population, it amounts to war crime and crime against humanity,” he added.


Security was increased across Islamabad ahead of the expected arrival of foreign delegations.

Islamabad Police said that the Red Zone and Extended Red Zone were completely closed for all kinds of traffic due to the arrival of foreign delegations. Public and heavy transport were also suspended until further orders.

Sources told a private media outlet that advance teams had already landed at Nur Khan Airbase, where at least three US cargo planes arrived. The teams were later moved to the High Security Zone under strict security arrangements.

Luxury hotels in Islamabad were also asked to vacate rooms for foreign VVIPs, delegates and their teams, with guests directed to leave by Sunday afternoon.

Around 67 points in and around the High Security Zone, including the Red Zone, were sealed with barriers, while Rangers and security personnel were deployed across routes leading to key locations.

In Rawalpindi, roads around Nur Khan Airbase were blocked with containers and barbed wire, while Metro Bus Service between Rawalpindi and Islamabad and electric bus services were suspended.

“All private, public and goods transport in Rawalpindi suspended from 12 noon till further orders,” Deputy Commissioner (DC) Hassan Waqar Cheema said.

Tensions also increased after Iran reportedly launched drone strikes on US military vessels in the Gulf of Oman after the US Navy seized an Iranian-flagged container ship.

Iran’s Khatam al-Anbiya Central Headquarters described the US naval operation as a violation of the ceasefire and stated that it would “retaliate for this act of armed piracy by the US Navy”.
