Senior officer from Golani Brigade dies after failed attempt to rescue injured troops in Shejaiya area

• Israel-Gaza war – live updates

Two senior Israeli commanders and seven other soldiers have been killed by Hamas in a complex ambush in the Gaza City suburb of Shejaiya, an area that has seen intense urban fighting in recent days.

The latest Israeli combat deaths came amid fears of a rapidly escalating humanitarian crisis in Gaza as heavy winter rains lashed the region and after reports by aid agencies of dwindling food stocks for the vast number of Palestinians who have been displaced to southern Gaza.

Reports are coming in from the Reuters news agency that three Palestinians were killed on Tuesday during an Israeli raid on the occupied West Bank city of Jenin – that’s according to the Palestinian health ministry.

An Israeli drone attack killed the three Palestinians and injured others, medical sources say, adding that the Israeli raid included the city of Jenin and its refugee camp.

Between the afternoons of 10 and 11 December, 208 Palestinians were killed and another 416 were injured, according to the [Hamas run] Ministry of Health (MoH) in Gaza. Heavy Israeli bombardments from air, land, and sea across Gaza continued, especially in the central part, including Al Maghazi and An Nuseirat Refugee Camps, as well as in parts of northern Gaza. Meanwhile, intense ground operations and fighting between Israeli forces and Palestinian armed groups continued, especially in Khan Younis, Jabalya, and the northern parts of Gaza Strip. Additionally, air strikes have reportedly targeted residential homes in the western and central parts of Rafah, areas designated as safe for displaced Palestinians by the Israeli army. The firing of rockets by Palestinian armed groups into Israel also continued.

Limited aid distributions are taking place in Rafah governorate. In the rest of the Gaza Strip, aid distribution has largely stopped over the past few days, due to the intensity of hostilities and restrictions of movement along the main roads, except for limited fuel deliveries to key service providers and a one-off high-risk mission on 9 December to Al Ahli hospital.

On 11 December, as of 22:00, 100 trucks carrying humanitarian supplies entered Gaza from Egypt, the same volume recorded on most days since the resumption of hostilities on 1 December. This is well below the daily average of 500 truckloads (including fuel) that entered every working day prior to 7 October. The ability of the UN to receive incoming aid has been significantly impaired over the past few days by several factors. These include a shortage of trucks within Gaza; the continuing lack of fuel; telecommunications blackouts; and the increasing number of staff who were unable to travel to the Rafah crossing due to the intensity of hostilities.

WHO chief says Gaza’s health system is ‘on its knees and collapsing’ amid intensifying ground offensive

• Israel-Hamas war – live updates

Israel has rejected suggestions it is trying to force Palestinians out of Gaza as Arab leaders and aid officials warn its intensifying ground offensive could leave civilians with few other options.

Some of the heaviest close-quarters fighting in more than two months of conflict took place over the weekend, as the Israel Defense Forces tried to consolidate control of urban centres in northern Gaza and pursued Hamas leaders in the heart of the biggest city in the south, Khan Younis.
