Israeli forces have stepped up their assault on Gaza City with a wave of heavy air strikes, marking a sharp escalation from previous military operations.

Unlike earlier phases of the war, the current offensive has relied heavily on aerial bombardments, with entire apartment blocks and large concrete structures reduced to rubble.

The intensification of strikes in recent days has triggered a surge in civilian displacement.

Israel has warned all residents of Gaza City to leave immediately in anticipation of a huge ground offensive.

On Saturday, the Israeli Defense Forces (IDF) said about 250,000 people had left the city and moved south. It also said it had destroyed a high-rise building that it claimed was used to execute terrorist attacks against its troops.

Israeli Prime Minister Benjamin Netanyahu insists that Gaza City is Hamas's last major stronghold, bringing international criticism regarding the plan to occupy it.

The UN has cautioned that escalating the offensive in an area already declared a famine will intensify the humanitarian crisis.

Residents report that the military targets schools and makeshift shelters, often issuing warnings just moments before the attacks, forcing families to flee in darkness.

We escaped certain death, my husband, our three children and I, said Saly Tafeesh, describing her harrowing escape.

Israeli forces have urged evacuating civilians to head south, but many families are unable to afford the journey, which can cost up to $1,100 (£800). Hamas has responded by urging residents to stay and resist leaving.

Rubein Khaled, a father-of-nine, shared his frustration regarding the evacuation calls made by local religious leaders, questioning why they don't urge Hamas to cease hostilities and negotiate peace.

As the offensive continues, Palestinians express fears that the relentless attacks could dismantle entire neighborhoods of the city.

The humanitarian situation has further deteriorated, with reports from the Hamas-run health ministry indicating numerous casualties from starvation amid ongoing conflict.
