Israel has carried out a wave of air strikes across the Gaza Strip, triggering the mass displacement of hundreds of Palestinian families, witnesses say.

Rescue teams recovered the bodies of five people, while dozens of injured civilians were evacuated to Al-Ahli Hospital in Gaza City, according to local reports.

The bombardment follows one of the largest evacuation orders issued since the war resumed in March.

It comes amid increasing pressure on Israeli Prime Minister Benjamin Netanyahu to refocus efforts to reach a ceasefire agreement.

Residents in Gaza City said dozens of Israeli air raids targeted densely populated eastern neighbourhoods, including Shujaiya, Tuffah, and Zeitoun.

Videos posted by activists on social media captured scenes of chaos and explosions illuminating the night sky, followed by flames and thick plumes of smoke rising above the skyline.

One of the strikes reportedly hit a school in Zeitoun that had been sheltering displaced families.

The five fatalities reportedly occurred in a strike at the Al Shati camp, to the west of Gaza City.

The Israel Defense Forces (IDF) had earlier ordered residents to leave large parts of northern Gaza, in anticipation of the attacks. Most of those displaced overnight moved westwards within Gaza City rather than to the southern region as instructed by the IDF.

"We had no choice but to leave everything behind," said Abeer Talba, a mother of seven who fled Zeitoun with her family.

"We got phone calls recordings in Arabic telling us we were in a combat zone and must evacuate immediately.

"This is the seventh time we've been forced to flee," she added. "We're in the streets again, no food, no water. My children are starving. Death feels kinder than this."

Amid the growing humanitarian crisis, fears are mounting that the evacuation orders and sustained air strikes are part of a broader Israeli plan to expand its ground offensive deeper into Gaza.

But there is also speculation in Israeli media that some generals are close to concluding that military operations in Gaza are near to being achieved.

That is also the view of many former army leaders who fear that the descent of the Gaza campaign into more attritional, guerilla-style warfare would lead to more deaths – of hostages, civilians and soldiers.

The Israeli prime minister's next moves are being closely watched. While Benjamin Netanyahu's instincts have always been to continue the war and defeat Hamas, he is coming under increasing pressure at home and abroad to pursue a new ceasefire agreement.
