President Donald Trump is indicating that there has been progress with Iran on its nuclear program and hinted that an announcement could come in the “next two days.”

In return for curbs on its nuclear programme, Iran had received relief from international sanctions. But the accord was torpedoed in 2018 when Trump unilaterally withdrew the United States and reimposed sanctions. A year later, Iran responded by ramping up its nuclear activities.

Iran and the United States will hold talks Friday in Rome, their fifth round of negotiations over Tehran’s rapidly advancing nuclear program.
