Trump says Iran's proposal 'totally unacceptable', accuses Tehran negotiators of 'playing games'

Diplomatic efforts between the US and Iran appeared to stall again even as a fragile ceasefire holds across a region still rattled by weeks of strikes, naval incidents and mounting economic pressure.

Overnight on Sunday and into early Monday (may 11, 2026), US President Donald Trump stated in a socmed post that Iran's proposal is "totally unacceptable" after Tehran responded to Washington’s latest proposal for ending the war.

Trump sharply criticised Tehran’s latest reply to a proposed framework for de-escalation, calling it “totally unacceptable” and accusing Iranian negotiators of “playing games.”

His remarks underscored how far apart the two sides remain on the terms of any longer-term settlement, despite backchannel talks meant to prevent the conflict from spiraling into a broader war.

The impasse comes as both governments attempt to define what a post-ceasefire landscape should look like.

Tasnim, citing an informed source, stated: “Trump’s reaction is of no importance. No one in Iran is working on formulating a plan to satisfy the American president.”

Washington has signaled that any durable agreement must address Iran’s nuclear program, its missile capabilities and its role in regional waterways. Tehran, meanwhile, has insisted that sanctions relief and recognition of its maritime rights must come first.
