In the north of the Hamas-ruled Palestinian enclave, Israel said its forces were still present at Gaza’s biggest hospital, Al Shifa, but gave no further details of their operations since the previous day when they entered the facility culminating a days-long siege.

Reuters was unable to verify the situation at Shifa on Thursday morning, having lost contact with doctors inside it since Wednesday.

Leaflets dropped overnight from aircraft told civilians to leave the towns of Bani Shuhaila, Khuzaa, Abassan and Qarara, on the eastern edge of Khan Younis, the main southern city. The towns, collectively home to more than 100,000 people in peacetime, are now sheltering tens of thousands more who fled other areas.
