several high ranking officials in Iran have asked Khamenei to declare Iran to be in state of war with Israel
Since Israel bombed Iranian consulate and openly admitted doing this, it's Iran's right to see that an act of war of agression that gives Iran the right to self defense against an aggressor is granted to Iran under Article 51 of the UN charter:
Article 51
“Nothing in the present Charter shall impair the inherent right of individual or collective self-defence if an armed attack occurs against a Member of the United Nations, until the Security Council has taken measures necessary to maintain international peace and security. Measures taken by Members in the exercise of this right of self-defence shall be immediately reported to the Security Council and shall not in any way affect the authority and responsibility of the Security Council under the present Charter to take at any time such action as it deems necessary in order to maintain or restore international peace and security.”
