IRNA - A prominent law expert from Geneva's Graduate Institute of International and Development Studies in a message slammed the US officials' misunderstanding of the diplomatic freedom.

'Brian Hook [American lawyer and government official] says being out of the #JCPOA has given US a great deal of 'diplomatic freedom'. 'Diplomatic freedom' is a new term to describe acting outside Int'l law. Like #Saudi also enjoys its 'diplomatic freedom' when it bombs school buses, disregarding all laws of war in #Yemen,' Reza Nasri tweeted on Friday.

Earlier Iranian Foreign Minister Mohammad Javad Zarif in a message emphasized viability of ending war in Yemen.

“I said this on the crisis in Yemen in April 2015. Today, after untold human suffering & war crimes by the Saudi coalition & its US accomplices, & efforts to whitewash their crimes with absurd allegations against Iran, our four-point plan still remains the only viable option,' Zarif tweeted on Friday.

Saudi Arabia and a number of its regional allies launched a devastating military campaign against Yemen in March 2015, with the aim of bringing the government of Mansour Hadi back to power and crushing the country’s Houthi Ansarullah Movement.

Some 16,000 Yemenis have been killed and thousands more injured since the onset of the Saudi-led aggression.

The assaults of the Saudi-led coalition forces have failed to stop the Yemenis from resisting the aggression.
