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 . Jund Ansar Allah is part of the radical Islamist movement that follows the doctrines of the `` Salaf , '' or the predecessors -- referring to the early generations of Muslims . They reject all modern influences such as politics and government . In a televised statement , Hamas ministry spokesman Taher Nunu called al-Maqdessi 's group `` outlaws '' and said they have been `` terrorizing the country and attacking civilians . '' `` We hold the group and its leader fully responsible for what is happening in Gaza and we offer our condolences to everyone who was killed during the clashes , '' Nunu said . `` No one is above the law and we urge everyone who is a member of this group to surrender himself to the authorities or they will be accountable for all of their actions . '' The gunfight erupted near a mosque in the southern Gaza city of Rafah , where the cleric delivered his sermon , the sources said . Hamas militants raided the mosque and seized control of it . Later , the fighting spread to al-Maqdessi 's home , the sources said . Al-Maqdessi also called for a public meeting at the mosque , posting on the Jund Ansar Allah 's Web site an invitation dubbed `` the golden advice to the government of ( Hamas leader ) Ismail Haniya . '' The group posted a statement on the Web site announcing the establishment of the Islamic emirate in Gaza and proclaiming al-Maqdessi `` the commander of the faithful . '' The statement declared that armed forces in Gaza should unite under him . It urged Muslims everywhere to support the `` young emirate '' by providing money , weapons and men because `` this is the hope of the Muslim nation in raising the banner of monotheism in Palestine and to liberate all the lands and purify Al-Aqsa mosque from the filth of the damned Jews . '' Al-Aqsa mosque is in Jerusalem . The group accused Hamas of not being Islamic enough , saying they care more about pleasing `` tyrants '' than `` obeying God . '' But Hamas spokesman Sami Abu Zahri dismissed statements about the establishment of an Islamic emirate as `` theoretical . '' `` It is not permitted to any party or individual to enforce their own laws because this is the responsibility of the security forces , '' he said . CNN 's Talal Abu-Rahman in Gaza City , Gaza , contributed to this report .
