Tehran accuses Washington of "excessive demands" as US weighs fresh strikes amid stalled peace talks, while Pakistan’s army chief arrives in the Iranian capital to mediate.
Iranian officials reject the latest US peace proposal, calling Washington’s conditions "excessive," as American media report the Biden administration is preparing potential new military strikes, according to *France24* and *FAZ* liveblogs . The escalation follows 85 days of conflict, triggered by a US-Israeli attack on Iran on February 28, which led to a fragile ceasefire on April 7. Western Iran’s airspace remains closed, and tensions persist over the Strait of Hormuz, a critical oil chokepoint .
Pakistan’s army chief, General Asim Munir, arrived in Tehran on Saturday to revive negotiations, meeting Iranian Foreign Minister Abbas Araghchi late Friday in marathon talks, *CPH Post* and *Al Jazeera* report . Islamabad has positioned itself as a key mediator, with Munir’s visit coinciding with US Senator Marco Rubio’s acknowledgment of "slight progress" in backchannel discussions, though President Trump warned the talks "teeter on the edge" of collapse .
Regional powers are intensifying diplomatic efforts, with Pakistan leveraging its ties to both Washington and Tehran. *Radio Free Europe* notes Beijing’s role in hosting parallel talks, reflecting China’s growing influence in brokering Middle East conflicts . However, Iran’s Supreme Leader Ali Khamenei has publicly dismissed US demands for concessions on nuclear enrichment and regional proxy forces, deepening the stalemate.
With the ceasefire holding but no formal agreement in sight, analysts warn the window for diplomacy is narrowing. The Pentagon has not confirmed reports of planned strikes, but *Brussels Morning* describes the current phase as "dangerous and unpredictable," with financial markets reacting to the heightened risk of renewed hostilities . The next 48 hours are critical, as Munir’s shuttle diplomacy and Iran’s response to the US proposal could determine whether the conflict escalates or de-escalates.
