Hamas is a Palestinian armed group and political movement in the Gaza Strip. On 7 October 2023 it attacked Israel, killing about 1,200 people and taking more than 250 hostages. This triggered a massive Israeli military offensive in Gaza, which has killed tens of thousands of Palestinians.

The war against Hamas, which began in the wake of its attack on Israel on October 7, 2023, was one of the longest sustained wars that Hamas has had to face in its almost 40-year history. The group was prepared to face this challenge.
