Lebanon's Shiite movement Hezbollah is fighting the jihadist Islamic State group in Iraq, its chief Hassan Nasrallah revealed for the first time Monday in a speech beamed to supporters in southern Beirut.


"We may not have spoken about Iraq before, but we have a limited presence because of the sensitive phase that Iraq is going through," Nasrallah said in reference to ongoing clashes between Iraqi troops, several militias and Kurdish forces against the IS.

Hezbollah is already fighting in Syria, alongside President Bashar al-Assad's forces.

Nasrallah's speech comes two days after his leading Lebanese opponent, Saad Hariri, called on Hezbollah to withdraw from Syria.

"I say to those who call on us to withdraw from Syria, let's go together to Syria," said Nasrallah.

"I say, come with us to Iraq, and to any place where we can fight this threat that is threatening our (Muslim) nation and our region," he added.
