Pakistan Races to Preserve US–Iran Diplomacy as Fragile Ceasefire Nears Breakdown

Pakistan is intensifying diplomatic efforts to prevent the collapse of the ceasefire between the United States and Iran, amid growing tensions and accusations surrounding Islamabad’s mediator role.

The crisis escalated after reports claimed Iranian military aircraft had been moved to Pakistan’s Nur Khan Air Base near Rawalpindi following the April 8 ceasefire, allegedly to shield them from potential US strikes.

Pakistan’s Foreign Ministry strongly rejected the allegations, describing the reports as “misleading and sensationalised.” Officials said the aircraft arrived as part of diplomatic logistics connected to high level talks held in Islamabad between US and Iranian officials on April 11.

“The Iranian aircraft currently parked in Pakistan arrived during the ceasefire period and bear no linkage whatsoever to any military contingency or preservation arrangement,” the ministry stated.

Islamabad also emphasized that both Iranian and US aircraft had used the facility during the mediation process and insisted that any significant foreign military deployment would be impossible to conceal.

The controversy emerged shortly after Donald Trump publicly declared that the ceasefire was on “massive life support,” rejecting Iran’s latest peace proposal as “totally unacceptable.”

Iran’s proposal reportedly demanded US war reparations, recognition of Iranian sovereignty over the Strait of Hormuz, the lifting of sanctions, and the release of frozen assets. Tehran also insisted that discussions surrounding its nuclear programme could only begin after sanctions and the US naval blockade were removed.

Iranian officials defended the proposal as “reasonable and generous,” while senior Iranian leaders warned that any renewed military escalation would trigger a strong response.

Concerns in Washington have also grown over Pakistan’s role as mediator. Some US officials reportedly questioned whether Islamabad was accurately conveying American concerns during negotiations.

However, Pakistani officials maintained that successful mediation requires neutrality rather than alignment with either side.

Analysts say Pakistan remains a critical diplomatic channel because both Tehran and Washington continue to engage with Islamabad despite rising distrust.

The ceasefire itself has remained fragile since the United States imposed a naval blockade on Iranian ports on April 13, an action widely viewed as undermining the truce.

While full scale conflict has not resumed, tensions in the Gulf region remain high, particularly around the Strait of Hormuz, where shipping disruptions and military incidents continue to raise fears of escalation.

Diplomatic activity is also expanding internationally. Qatar and China have both increased involvement in efforts aimed at stabilizing negotiations, while Iranian Foreign Minister Abbas Araghchi continues regional diplomatic outreach.

Meanwhile, Benjamin Netanyahu stated that military action remains an option if negotiations fail to address concerns surrounding Iran’s nuclear capabilities.

As diplomatic channels multiply, regional powers warn that the ongoing militarization of the Strait of Hormuz could have lasting consequences for global energy markets and regional stability.
