Iran calls Vance letter a 'positive' shift as Qatar-led mediation continues

On Sunday, Iran's security chief described a reported letter from US Vice-President JD Vance as signalling a positive change, in an effort to revive talks. Earlier, the US and Iranian foreign ministers said a diplomatic end to the war remains possible, and Iran's foreign minister said Iran and Qatar have discussed a plan to reopen the Strait of Hormuz within two days, provided the US meets Tehran's conditions. Alongside the diplomacy, Iran's supreme leader warned on Saturday that any response to an attack would not be limited by geography, and reports persist of a possible US move to resume strikes.

  • Araghchi said on Saturday that Iran does not rule out an attack and is prepared for all scenarios, while its delegation held talks in Qatar.
  • Iranian lawmakers on Saturday urged withdrawal from the nuclear Non-Proliferation Treaty; observers say leaving would not by itself mean Iran would build a weapon.
  • Pakistan's army said on Friday it is cautiously optimistic about mediation, and warned of 'powerful spoilers and detractors'.
  • Senators were briefed on Friday on Trump's reported plan to restart the war, and The Atlantic reported on Thursday that a top military planner was fired.
