Hamas is a Palestinian Islamic organization, with an associated military wing, the Izz ad-Din al-Qassam Brigades, in the Palestinian territories and elsewhere in the Middle East including Qatar. Hamas or its military wing is designated as a terrorist organization by Australia, Canada, Egypt, the European Union, Israel, Japan, the United Kingdom, and the United States, and is banned in Jordan. It is not considered a terrorist organization by Iran, Russia, Turkey,China, and some Arab nations. Based on the principles of Islamism gaining momentum throughout the Arab world in the 1980s, Hamas was founded in 1987 as an offshoot of the Egyptian Muslim Brotherhood. Co-founder Sheik Ahmed Yassin stated in 1987, and the Hamas Charter affirmed in 1988, that Hamas was founded to liberate Palestine, including modern-day Israel, from Israeli occupation and to establish an Islamic state in the area that is now Israel, the West Bank and the Gaza Strip. The group has later stated that it may accept a 10-year truce if Israel withdraws to the 1967 borders and allows Palestinian refugees from 1948, as well as their descendants, to return to what is now Israel.
