Hamas (UK: /hæˈmæs, ˈhæmæs/, US: /hɑːˈmɑːs, ˈhɑːmɑːs/; Arabic: حماس Ḥamās [ħaˈmaːs]), officially the Islamic Resistance Movement (حركة المقاومة الإسلامية Ḥarakah al-Muqāwamah al-ʾIslāmiyyah), is a Sunni Islamist political and militant organization currently governing the Gaza Strip of the Palestinian territories. While it is headquartered in Gaza City, it also has a presence in the West Bank (the larger of the two Palestinian territories), in which Fatah exercises control. It is widely considered to be the “dominant political force” within the Palestinian territories.
Hamas does govern the Gaza Strip.
