Gaza City, October 10: Over 180,000 Palestinians in the Gaza Strip are packed into United Nations shelters as Israeli warplanes pound the tiny territory of 2.3 million people after their Hamas militant rulers launched an unprecedented weekend attack on Israel. Among them is 27-year-old Sabreen al-Attar. She sprang into action when she heard rocket after rocket whoosh over her farmland in Beit Lahiya just south of the Israeli border on Saturday She knew from experience that Israeli retaliation would be swift and severe.

Grabbing her children, al-Attar rushed to one of the dozens of shelters set up in schools run by the UN agency for Palestinian refugees in Gaza City. There, blasts of unprecedented intensity punctuated hours of steadily declining conditions Monday as food and water ran out. “When I escape, I do it for my children,” she said, her hands trembling. “Their lives rest on my shoulders.” But residents say there is no real escape in Gaza, which has been under a suffocating 16-year blockade imposed by Israel and Egypt.

When war breaks out, as it has four times since the Hamas militant group seized power in 2007, even United Nations facilities that are supposed to be safe zones risk becoming engulfed in the fighting. The UN said that an airstrike directly hit one of its shelters Sunday and damaged five other schools-turned-shelters on Monday. There was no immediate word of casualties. In the downtown Rimal area, Gaza City's bustling commercial district with high-rises home to international media and aid organisations, al-Attar hoped she would be safe.

Rimal had until then not been an immediate Israeli target, unlike border towns or densely populated refugee camps. But as the Israeli military went neighbourhood to neighbourhood with rapid and intensifying airstrikes, the heavy bombardments reached the heart of Gaza City, transforming the affluent neighbourhood into an uninhabitable desert of craters.

Israeli bombs that struck Gaza's flagship Islamic University, government ministries and high-rises in Rimal, starting Monday afternoon, also blew out the windows of al-Attar's shelter, shattering glass everywhere, she said. Life there, crammed with 1,500 other families, was full of danger and deprivation but Al-Attar said she had no choice but to stay, telling her boys — 2-year-old Mohammed and 7-year-old Nabil — to keep away from the windows. “The night was very, very difficult,” she said Tuesday. “We have nowhere else to go.”

The bombing in Rimal and the potential risks of sheltering in UN schools highlighted the desperate search by Gaza civilians for refuge, with the territory's safe spaces rapidly shrinking. Ahead of the Israeli military's warning to civilians on Monday that Rimal would be hit, families staggered into the streets with whatever belongings they could carry and without a destination. In a briefing Tuesday, Israeli army spokesman Lt. Col. Richard Hecht suggested Palestinians should try to leave through the Gaza border crossing with Egypt — a seemingly impractical suggestion.

While Hamas officials operating the Gaza side of the Rafah crossing said Tuesday that Gazans who had registered in advance could cross into Egypt, the number of those allowed to travel has typically been small. That has led to backlogs and waiting times of days or weeks, even in calm times. “There is never a Plan B here,” said 31-year-old Maha Hussaini, as she watched terrified Rimal residents flood her Gaza City neighbourhood further south just as bombs began to fall there, too.

So far, the Gaza toll stands at about 700 dead and thousands wounded, according to Gaza health officials, a punishing response to the militant group's attack that has killed over 900 Israelis. More than 150 Israeli civilians and soldiers have been taken captive. Israel says it takes pains to avoid civilian casualties as it targets Hamas sites in Gaza. But the military long has carried out airstrikes in crowded residential neighbourhoods, inevitably harming civilians and civilian infrastructure. Hamas authorities on Monday reported the destruction of seven mosques and 15 civilian homes that killed many members of the same family.

The Israeli defense minister also has ordered a “complete siege” on the already blockaded Gaza Strip, vowing to block food, water and fuel from the territory. “None of us even know what safe' means in Gaza,” said 28-year-old Hind Khoudary, who was hunkered down in the upscale Roots Hotel as deafening explosions thundered. “These are not people with (militant) affiliations, these are people from higher classes, foreign organisations and media," she said of those around her. "But on days like this, there is zero difference.”

Residents described a dangerous dance around the heavy Israeli bombing — fleeing home, crashing at relatives' apartments, fleeing again to UN schools and then starting all over again in an attempt to find some sense of safety. “It is better than dying,” said 37-year-old Muhammad al-Bishawi, exhausted as he hustled between a UN shelter in Gaza City and his home in Beit Lahiya to secure food and other supplies before returning.

On Saturday after the massive Hamas attack, Israeli Prime Minister Benjamin Netanyahu warned Gaza civilians of the horrors to come, promising to unleash the full force of the Israeli military on the strip. “Get out now,” he said, addressing Palestinians in Gaza. “Because we will operate everywhere.” Khoudary was listening to him as the airstrikes intensified, trapped in her home with nowhere to run. “Why didn't he tell us where to flee?” she asked. “Because we'd really like to know.”
