Trump says 'a whole civilisation will die tonight' if Iran does not make a deal

US President Donald Trump once again exhorted Iran to make a deal by his Tuesday deadline, saying a "whole civilisation will die tonight" if an agreement is not reached to end the conflict.

"A whole civilisation will die tonight, never to be brought back again. I don’t want that to happen, but it probably will," Trump said in a post on Truth Social, reports Reuters.

"We will find out tonight, one of the most important moments in the long and complex history of the World."
