Heavy Israeli bombardment from air, land, and sea continued across much of the Gaza Strip, including central Gaza, the southern town of Khan Younis, and Jabalya Camp in northern Gaza. The firing of rockets by Palestinian armed groups into Israel also continued. Additionally, ground operations and fighting between Israeli forces and Palestinian armed groups were reported, including in areas such as Al Bureij and Al Maghazi camps in Deir al Balah, where Palestinians have relocated following orders from Israeli forces to move from northern Gaza, and the Ad Darraj and At Tuffah neighbourhoods of Gaza city. Reportedly, these operations resulted in high numbers of fatalities.
On 4 January, the vicinity of Al Amal hospital and Palestine Red Crescent Society (PRCS) in Khan Younis was struck for the third consecutive day. PRCS reported that seven IDPs (internally displaced people) sheltering in the compound, including a five-day-old baby, had been killed, while another 11 people were injured over the three days of bombardment. PRCS also reported that dozens of residential buildings and people gathered at the entrance of Al Amal Hospital had been hit, resulting in dozens more deaths and injuries.
