Explainer | What is Hamas? Israel at war with militant group that rules Gaza
- Hamas has ruled Gaza since 2007 and is designated as a terrorist organisation by the US, EU and other Western countries
- Militant group has a history of violence, including suicide bombings and rocket attacks, and has called for the annihilation of Israel

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.
The group has vowed to annihilate Israel and has been responsible for many suicide bombings and other deadly attacks on civilians and Israeli soldiers.
