Israeli forces were expanding their offensive in Gaza on Sunday, taking control of more territory and issuing fresh evacuation orders for residents who had only recently returned to their homes.

The Israeli military renewed its offensive in Gaza this past week after talks to extend a fragile, temporary cease-fire that came into effect in mid-January reached an impasse. On Sunday, it said that those operations had moved into additional areas in the north and south of the enclave.

Israel said that its troops had begun operating in Beit Hanoun, in northern Gaza, to expand a buffer zone. The military also said that it had carried out more airstrikes against Hamas targets and infrastructure and that it was allowing people to evacuate.

The military also separately issued an evacuation order for the Tal al-Sultan neighborhood of the southern city of Rafah, telling residents to leave on foot along a specific route and barring the movement of vehicles.

The Rafah municipality said in a statement that thousands of families were being forced to flee on foot under bombardment during the holy Muslim fasting month of Ramadan. That left them homeless amid a severe shortage of basic necessities and tents because of the Israeli government’s closure of the crossings into Gaza, the municipality noted.
