The Hezbollah Brigades in Iraq have called for preparing for an all-out war in support of Iran.
The Secretary-General of the Hezbollah Brigades, Abu Hussein al-Hamidawi, said:

"We direct our appeal to the brothers in jihad across the East and West, to everyone whose heart is filled with faith, who loves God and His Messenger, and who is convinced that honor belongs to God, His Messenger, and the believers. To everyone who refuses to let the front of disbelief and hypocrisy dominate the people of faith and justice: prepare yourselves for an all-out war in support of and backing for the Islamic Republic of Iran, the fortress of the nation and its pride, which for more than four decades has stood by the oppressed and all the just causes of the nation of Muhammad (peace be upon him and his family), without regard to sect, color, or ethnicity."

He added:
"Today, the forces of misguidance—Zionists and their tyrants—are gathering to try to subjugate it, indeed to destroy it and demolish all moral and ethical foundations on earth. While we stress the necessity of supporting it from the forces of the Axis and backing it with whatever they can, we affirm to the enemies that war against the Republic will not be a picnic. You will taste deadly forms of death, and nothing of you will remain in our region. (We shall cast terror into the hearts of those who disbelieve)."

He continued:
"And we say to our dear brothers in jihad: be prepared on the ground for this, and ready yourselves for one of the two noble outcomes—especially if jihad is declared by the honorable religious authorities to wage this sacred war, with all that it entails of rulings or jihadist actions that may rise to martyrdom operations, in defense of the people of Islam and its core. (So fight the leaders of disbelief, for indeed they have no faith)."
