Hamas, which has ruled the Gaza Strip since 2007, launched an attack inside Israel over the weekend, killing hundreds and taking others hostage. Its unprecedented breach of the border sent fighters inside border communities and military installations, shocked Israel and its allies, and raised questions about the group's capabilities and strategy.
What is Hamas?
The group was founded in 1987 by Sheikh Ahmed Yassin, a Palestinian refugee living in Gaza, during the first intifada, or uprising, which was marked by widespread protests against Israel's occupation.
Hamas is the Arabic acronym for the Islamic Resistance Movement, and a recognition of the group's roots and early ties to one of the Sunni world's most prominent groups, the Muslim Brotherhood, founded in Egypt in the 1920s.
