Ambassador and Permanent Representative of Iran to the United Nations (UN) Majid Takht Ravanchi in a message urged the UN Secretary-General and the UN Security Council to condemn state-sponsored assassination of Iranian scientist Mohsen Fakhrizadeh.
"What was clearly a state-sponsored assassination of our prominent scientist was also a clear violation of int'l law, designed to wreak havoc on our region," Takht Ravanchi wrote in his Twitter account on Saturday.
"It must be condemned by #UNSG & #UNSC," he added.
"Iran wont ever shy away from deterring aggression, or from protecting its people," he noted.
Fakhrizadeh was assassinated in a terrorist attack near Tehran on Friday.
