GAZA CITY, Gaza (CNN)  -- A radical Muslim sheikh's call for the creation of an Islamic emirate in Gaza sparked clashes with Hamas forces that left 21 people dead and injured at least 121 others. Members of Jund Ansar Allah surround Sheikh Abu al-Nour al-Maqdessi in Rafah on Friday. Hamas forces blew up the home of Sheikh Abu al-Nour al-Maqdessi, leader of the radical group Jund Ansar Allah, or Soldiers of the Partisans of God, Hamas sources said. Al-Maqdessi, also known as Abdel Latif Musa, was among the 21 dead, a hospital spokesman told CNN. Friday's clashes were the latest between Gaza's Hamas rulers, who have said they are moderate Muslims pledged to the Palestinian cause, and more extremist Islamic groups.
