Umm al-Fahm
The Triangle is further divided into the "Northern Triangle" or Wadi Ara (around Kafr Qara, Ar'ara, Baqa al-Gharbiyye, Zemer and Umm al-Fahm) and the "Southern Triangle" (around Qalansawe, Tayibe, Kafr Qasim, Tira, Kafr Bara and Jaljulia). Umm al-Fahm and Tayibe are the social, cultural and economic centers for Arab residents of the region. The Triangle is a stronghold of the Islamic Movement in Israel and Raed Salah, the current leader of the movement's northern faction, is a former mayor of Umm al-Fahm.
