“The behavior of representatives of the Islamic State is a horrible challenge to us all,” Patriarch Kirill said on February 19, according to an Interfax report. “No one can do a more horrible thing to Islam than what they are doing.”
Muslim leaders, he added, “should not think solely about their currently political goals. Especially when they support ISIS, directly or indirectly, they should clearly understand that it is a blow to the entire Islamic world above all.”
