Iran nuclear deal set for reprieve as Donald Trump prepares to extend waivers

Donald Trump is to extend waivers on Iran sanctions, keeping the landmark 2015 nuclear deal alive for at least another few months despite his vows to scuttle the deal, according to sources in Washington.

The waivers are due to be announced later, and will be accompanied by other targeted sanctions on Tehran and a stern warning that the president will pull out of the deal negotiated by the Obama administration if fixes are not made by spring.
