Iran cuts direct diplomacy with US amid rising tensions ahead of Trump's deadline

Iran has cut off direct communications with the US following President Donald Trump's threat to destroy Iran's "whole civilization," media reports said on Tuesday.

The move came ahead of a Tuesday deadline set by Trump for a potential agreement, complicating efforts to reach a deal but not ending ongoing negotiations, according to The New York Times, citing three Iranian officials.

Officials said indirect talks through ceasefire mediators are continuing despite the suspension of direct contact, according to the reporting, which was largely confirmed by The Wall Street Journal.

One official said Iran's decision was intended to send "a signal of disapproval and defiance" in response to the threat, according to the outlet.

It remains unclear whether direct communication between Tehran and Washington will resume before the deadline.

The White House did not immediately respond to requests for comment.

Trump earlier warned that "a whole civilization will die tonight, never to be brought back again" — remarks that fueled speculation as his 8 pm Eastern Time (0000GMT Wednesday) deadline for Iran approaches.
