Iranian Foreign Minister Mohammad Javad Zarif blamed former US President Donald Trump in violation of the US obligations under the Iranian deal (JCPOA) three years ago and called him a "disgraced buffoon," Iran Press reported.
"As we try to revive JCPOA in Vienna, it's necessary to remember how it all started. 3 years ago today, a disgraced buffoon violated US obligations under JCPOA & UNSCR 2231. Today, @POTUS has to decide whether US continues lawlessness or adheres to law. Onus is on US, not Iran," he tweeted.
