A "complete siege" is a term used to describe a situation where a region or territory is completely cut off from the outside world, with no supplies or resources allowed in or out. In the context of recent events, the Israeli Defense Minister Yoav Gallant ordered a "complete siege" on Gaza, which involves halting the entry of food, fuel, and supplies to its 2.3 million people. The order was given in response to a surprise attack by Hamas militants, and the Israeli military has been conducting airstrikes and clashes with Hamas militants in the area. The situation has left many concerned about the humanitarian impact on the people of Gaza, who are already facing difficult living conditions.
