A leading Jordanian jihadist ideologist on Wednesday de**unced the declaration of a "caliphate" by Sunni militants in Iraq and Syria, warning against more bloodshed. "Can every Muslim and weak person find refuge in this caliphate? Or would it be like a sharp sword against all opponents?" Issam Barqawi, k**wn as Abu Mohammed al-Maqdessi, wrote on Facebook and on jihadist websites. On Sunday, militants previously k**wn as the Islamic State of Iraq and the Levant (ISIL), declared a "caliphate", an Islamic form of government last seen under the Ottoman Empire, straddling parts of Iraq and Syria.
