The US say it was a decisive defence action, claiming the IRGC commander was planning attacks on American citizens in Iraq.
“Certainly the momentary joy of the Americans and Zionists will not last long and will turn into mourning,” Sharif said.
“The Israelis and Americans have committed a blatant crime at odds with all international regulations and laws and they should rest assured thatt hey will receive a tough response,” he promised.
Iran has always seen Israel as a key enemy, a representation of its hatred for the US in the Middle-East.
It has also blamed the Jewish state for attacks on its territory.
Sharif said although IRGC members are currently in mourning, “their determination to take revenge on the usurper Zionist and criminal America will be greater”.
He added that the IRGC will “begin a new chapter” after the death of Soleimani and that there are many eager to carry on his legacy.
