On 9 October 2023, Israel intensified its blockade of the Gaza Strip when it announced a "total blockade", blocking the entry of food, water, medicine, fuel and electricity after the October 7 attacks and the ensuing Gaza war. The blockade has been credited with contributing significantly to the Gaza genocide. Israel has conditioned its lifting of the blockade with the return of the hostages abducted by Hamas, which has been criticized as collective punishment and an apparent war crime. As of August 2025, 27 European countries and over 100 international aid organizations have called for an end to Israel's blockade of aid into Gaza.
A few weeks after 9 October 2023, Israel eased the complete blockade, but still continued to severely restrict the amount of aid entering the Gaza Strip. The first supplies entered on 21 October 2023. The blockade exacerbated Gaza's humanitarian crisis. In January 2024, Israeli authorities blocked 56% of humanitarian aid to northern Gaza. On 9 February 2024, UNRWA's director Philippe Lazzarini said that Israel had blocked food for 1.1 million Palestinians in Gaza.
