In Gaza's crowded Khan Younis, 90 people shelter in one house

Ibrahim AlAagha, who was visiting Gaza from Ireland, fled with his family to his parents' house in the south

Ibrahim AlAgha and his wife Hamida had been enjoying an extended holiday in Gaza when Israeli air strikes on the territory began.

The couple, who are Irish citizens, had wanted their three Dublin-born children to get to know their Palestinian relatives and learn about the language and culture.

But instead of the relaxed family gatherings they had expected to round off their trip, the family had to contend with strikes and explosions.

"It was... constant bombing, bombing, bombing and the house [was] shaking," Ibrahim says.

Israel launched retaliatory strikes on Gaza after an attack by Hamas gunmen on 7 October killed at least 1,400 people. So far, 9,000 people in Gaza have also been killed, according to the Hamas-run health ministry.

After Israel told 1.1 million people to head south ahead of an expected ground invasion, the family packed up their belongings in their apartment in Gaza City and left. They took shelter in Ibrahim's parents' house in the southern city of Khan Younis.

As more people fled south, they were joined by relatives and friends with no place to stay and the house is now home to 90 people. His family, Ibrahim says, would never turn anybody away.

Life for 90 in a four-bedroom home is not easy. The group moved some of the furniture outside to make room for makeshift beds. They sleep in shifts, with two to a mattress. Ibrahim, an engineer, removed the windows from their frames to prevent glass from injuring people in the event of a possible drone attack. But with food, water and electricity in short supply in Gaza, no-one can ever relax.

"From the time we wake up to the time we sleep, we're just trying to survive," he says.

Ten of the children staying in the house are under five

Some of the group try to go out every day to see if canned food is being distributed. Though they can bake bread in a neighbour's wood oven with their dwindling supplies of wheat, there is not enough for more than one meal a day.

The shortages are especially hard on the 30 children - 10 of whom are under five.

"They always ask for food and water, and we're trying to get them as much as we can... It's very difficult.

"Elderly people, we can bear it a bit, we can stay hungry, but when children are asking for food we can't say no to them."

The house is attached to a farm, which has a well. The group has managed to extract water from it using an electric generator and though it is salty and unfiltered, Ibrahim says they have no option but to drink it.

He is concerned about the health of the group, which includes a pregnant woman and an elderly diabetic man who he says will run out of medicine soon. If anyone gets seriously ill, he fears the group will not be able to get medical attention for them in Gaza's crowded hospitals.

'My son is really worried'

And Ibrahim's own children have been deeply affected by the events. Omar and Eileen - aged just three and four - get frightened when they hear a strike or an explosion, and Ibrahim and his wife try to distract them by playing games and reading stories.

At night, the commotion can interrupt their sleep and they sometimes wake up screaming. Eight-year-old Sami is missing his teacher and his school in north Dublin and is scared by the worsening situation.

"He understands what's going on… he can hear and feel the frustration we are going through and he is really worried."

While conditions in Gaza deteriorate, Ibrahim and his family have been trying their best to get back to Dublin and are in contact with the Irish Department of Foreign Affairs about an evacuation. On Saturday, they took a "very risky" journey from Khan Younis to the Rafah border crossing with Egypt - one of the two land routes out of the Gaza Strip. Thousands of people have gathered there to try to leave Gaza.

But when they got to the border, Ibrahim says they received a message from the Irish Embassy in Tel Aviv instructing them to turn back because the Rafah crossing was not going to open. Now he worries he might not have enough fuel to be able to reach the border again if another evacuation plan goes ahead. Even if he does have fuel, he may lose communication with the embassy if phone networks die.

"I'm starting to lose hope," he says.

The Irish Deputy Prime Minister Micheál Martin has said the government is working to assist Irish citizens in Gaza. In the meantime, the family face an agonising wait.

After an explosion hit the Al-Ahli Arab hospital in Gaza City on Tuesday, in which hundreds are feared to have been killed, Ibrahim says no-one in their crowded Khan Younis house could sleep.

"We are really fearing for our lives... there's no limits… anyone, anywhere could be targeted.

"Things are getting worse every day."
