Zarif: New US sanctions would 'unravel' Iran nuclear deal
None
Iran warned the US Congress on Friday against imposing new sanctions, saying this would lead to a collapse of negotiations over Iran's controversial nuclear programme.
"We have an agreement that has the prospect of reaching a comprehensive agreement. If someone comes to torpedo (the agreement), I believe (the person or entity) should be isolated by the international community, whether it's the US Congress or anybody else," Iran's Foreign Minister Mohammad Javad Zarif told a meeting of political and business leaders in Davos.
