The U.S. and Iran are set to enter the next phase of the nuclear talks to achieve an agreement that would guarantee that the country does not have nuclear weapons or remain under the constraint of sanctions,

At risk is a possible American or Israeli military strike on Iran’s nuclear sites, or the Iranians following through on their threats to pursue an atomic weapon.

The Iranian foreign minister said Saturday that the next round of talks with the United States over Iran's advancing nuclear programme will be in Oman with US envoy Steve Witkoff on April 26. But experts will meet there in the days before.
