Gaza humanitarian crisis (2023–present) in the context of "António Guterres"

The Gaza war has disproportionately affected children in the Gaza Strip, where they make up about 40% of the population. From the start of the war, large numbers of children were killed. Early in the war, UN secretary general António Guterres warned that "Gaza is becoming a graveyard for children. Hundreds of girls and boys are reportedly being killed or injured every day." As the war continued, the toll increased steadily, and by 3 September 2025 at least 19,424 children had been reported killed.

Within the first month of the war, about 700,000 children in Gaza had been displaced. In May 2025, it was estimated that at least 1.9 million people, roughly 90% of Gaza’s population, had been displaced by the war. Many had been uprooted repeatedly, in some cases more than ten times. The collapse of essential services created a humanitarian crisis, as families struggled to access food, clean water, and medical care. The ongoing crisis also impacted routine vaccinations, leaving thousands of children at risk of preventable disease. Additional hardships included inadequate shelter, a lack of adequate winter clothing, and the continuing psychological toll on children's mental health.

The Rafah offensive was an Israeli military offensive in and around the city of Rafah, beginning on 6 May 2024 as part of Israel's invasion of the Gaza Strip during the Gaza war. The operation focused on the Rafah Governorate along the Egypt–Gaza border, with Israeli officials saying the goals were to defeat remaining Hamas forces in the area and to secure the border corridor and the Rafah crossing with Egypt.

The operation began as ceasefire negotiations brokered by Egypt and Qatar failed. Israeli forces carried out airstrikes, entered the outskirts of Rafah, and seized the Rafah crossing, later moving into populated neighbourhoods. Fighting and security concerns also led to temporary closures of the Kerem Shalom and Rafah crossings further exacerbating the humanitarian crisis in Gaza.

During the Gaza war, the healthcare system of Gaza was destroyed by Israeli attacks on hospitals and health facilities, killing of healthcare workers, and blockade of medical supplies from entering Gaza. The resulting collapse of the healthcare system was part of a broader humanitarian crisis in the Gaza Strip caused by the war.

The hospitals faced a lack of fuel due to the Israeli siege and relied on backup generators for the first two weeks of the war. By 23 October 2023, Gaza hospitals began shutting down as they ran out of fuel, starting with the Indonesia Hospital. When hospitals lost power completely, multiple premature babies in NICUs died. By the end of May 2024, both the World Health Organization and International Rescue Committee reported only one-third of Gaza's hospitals remained at least partially operational.

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.

A significant number of attacks on healthcare facilities occurred during the Gaza war and genocide. During the first week of the war, there were 94 attacks on health care facilities in Israel and Gaza, killing 29 healthcare workers and injuring 24. The attacks on healthcare facilities contributed to a severe humanitarian crisis in Gaza. By 30 November, the World Health Organization documented 427 attacks on healthcare in the West Bank and Gaza Strip, resulting in 566 fatalities and 758 injuries. By February 2024, it was reported that "every hospital in Gaza is either damaged, destroyed, or out of service due to lack of fuel." By April, WHO had verified 906 attacks on healthcare in Gaza, the West Bank, Israel, and Lebanon. As of June 2024, according to WHO, Israel has carried out 464 attacks on health care facilities, resulting in the death of 727 health care workers, injury of 933 health care workers, and damaging or destroying 113 ambulances.

Each side has been accused of committing war crimes in their attacks. CNN quoted the ICRC saying that "hospitals are given special protection under international humanitarian law in a time of war, but if militants store weapons there, or use them as a base of fire, then that protection falls away". Human Rights Watch stated, "The Israeli government has put forward no evidence that would justify stripping hospitals of their special protections." In December 2024, Andrew Cayley of the International Criminal Court said that Israeli claims about Hamas use of hospitals are "grossly exaggerated". On 13 March 2025, a United Nations investigation concluded that Israel has committed genocidal acts in Gaza by systematically destroying its reproductive healthcare facilities.

The Application of the Convention on the Prevention and Punishment of the Crime of Genocide in the Gaza Strip (South Africa v. Israel) is an ongoing case that was brought before the International Court of Justice on 29 December 2023 by South Africa regarding Israel's conduct in the Gaza Strip during the Gaza war, that resulted in a humanitarian crisis and mass killings.

South Africa alleged that Israel had committed and was committing genocide in Gaza, contravening the Genocide Convention, including what South Africa described as Israel's 75-year apartheid, 56-year occupation, and 16-year blockade of the Strip. South Africa requested that the ICJ indicate provisional measures of protection, including the immediate suspension of Israel's operations. Israel characterized South Africa's charges as "baseless", accusing the country of "functioning as the legal arm" of Hamas. Israel said that it was conducting a war of self-defense in accordance with international law following the Hamas-led attack on its territory on 7 October 2023.

During the Gaza war, humanitarian aid entered into the Gaza Strip via air, land and sea. Early in the war, significant issues arose with humanitarian aid. Israel's initial blockade on Gaza, immediately following the 7 October attacks, prevented the entry of humanitarian aid for several weeks. As the war progressed, aid was allowed at limited quantities. Entities such as Oxfam, the European Union, United Kingdom, and United Nations stated that Israel is deliberately blocking humanitarian aid. These limitations have contributed to a severe humanitarian crisis and a risk of famine. Israeli airstrikes and continued restrictions on aid entry led to widespread shortages of food and supplies. Distribution of aid within Gaza has also been an issue. Thousands of truckloads of aid piled up as armed men stop convoys, threaten drivers, and rifle through the cargo. Lawlessness was reported by PBS to be a major obstacle to aid distribution to southern and central Gaza. Gaza's police have refused to protect aid convoy after airstrikes killed eight police officers in Rafah.

Humanitarian aid agencies warned of the dire humanitarian consequences of aid restrictions, particularly after major Western donors announced they would cease funding UNRWA, the major aid relief agency in Gaza, and Israel passed legislation to ban UNRWA from working in or with the State of Israel.
