Al-Rahi was accompanied by Gregorios III Laham, Patriarch of the Melkite Greek Catholic Church, Syriac Catholic Patriarch Youssef III Younan and Ignatius Aphrem II, the Patriarch of the Syrian Orthodox Church.
“We are heading to Erbil as a first step in the implementation of the statement issued by the patriarchs in their last meeting,” said al-Rahi at Rafik Hariri International Airport.
“The first and essential clause in the statement is our support for Christians who have left their houses because of the Islamic State and other terrorist organizations,” he added.
The clergymen are scheduled to meet with Chaldean Catholic Patriarch of Babylon and the Head of the Chaldean Catholic Church Louis Raphael I Sako upon their arrival to Erbil.

The Vatican’s ambassador to the United Nations, Silvano Tomasi, had voiced support days earlier for U.S. air strikes, in a rare exception to papal policy promoting peaceful conflict resolution.
The United States has launched dozens of air strikes in Iraq since early August to support Iraqi and Kurdish forces pushing back IS militants in the north.
