Al-Azhar Grand Imam Ahmed el-Tayyeb condemned a terror attack against a Sunni mosque in Iraq, which left 70 people dead.
Tayyeb called on Iraqi religious leaders to decry the cowardly attack and work on spreading tolerance among Iraqis.
On Friday, Shiite militiamen gunned down 70 people in an apparent revenge attack at the Musab bin Omair Mosque in Diyala.
