A new report warns that the approach adopted by the US to kill off the 2015 Iran nuclear deal will not only lead to "serious consequences" for the multilateral accord, but also "do irreparable damage" to the UN Security Council.

UN diplomats say the US will have a tough challenge ahead if it pushes for an extension of the world body’s arms embargo on Iran by resorting to a process outlined in a nuclear deal it left in 2018.

Zarif rejects US threats to invoke the JCPAO’s snapback mechanism to reinstate UN sanctions.

The world is "no longer willing" to follow US demands and this is why the "snapback" of sanctions is almost impossible to implement, says an analyst.

Senator Shelley Moore Capito says it would be “next to impossible” to reverse the sanctions relief received by Iran.

An Iranian political commentator says a snapback mechanism envisaged in a UN Security Council resolution will hinder the JCPOA.
