Iranian Supreme Leader Ayatollah Ali Khamenei has urged the country's students to prepare for cyber war, the semi-official Mehr News Agency reported on Wednesday.

Khamenei delivered a message to a university students' association, or his "Revolutionary foster-children," as he called them, reminding them that they are "cyber-war agents" who must prepare for battle, Mehr reported.

"You are the cyber-war agents and such a war requires Ammar-like insight and Malik Ashtar-like resistance," he wrote according to Mehr, referring to two Prophet’s companions in early Islamic history. "Get yourselves ready for such war wholeheartedly."

Also Wednesday, Iran's Chief of Staff, General Hassan Firouzabadi, said his country is ready for a "decisive battle" with the U.S. and Israel, and dismissed threats against Tehran as "political bluffing."

“If any war is launched against Iran, we won’t give any ground to the enemy and they themselves know this very well," he said, according to Iran's semi-official Fars news agency.

He stressed that Tehran has made sure it is prepared for this "battle" against Washington and Tel Aviv by "staging different war games."
