Mr Alagha said: “We have elderly people living there, a pregnant woman and two people who have diabetes. They have insulin for now but, just like water and food, supply is limited.”
He added: “Last week we lost 11 members of our extended family when a bomb took out their homes and many people staying here have lost their properties.”
Each morning he is joined by several other men living in the clinic and they head out on bikes to the local bakery where long queues mean it can take hours to buy bread.
“On a normal day, we are probably eating as little as a third of what we would usually eat,” Mr Alagha said.
“And sometimes all we can have for the day is just plain bread.”
But on Monday, he arrived at the shop to find there was no bread and had no option but to return back to the property with nothing.
In an emotional video, shared with The Telegraph, Mr Alagha said: “There is no queue [at the bakery], no bread, no gas even.
“[The] problem is everyone is waiting for me now and I will go back home with nothing.
“No plans today for what we will have for food, we’ve nearly run out of everything. I don’t know what to say.”
Water and fuel run low
With water and fuel running low, the family and the rest of the household wonder how long it can endure its current circumstances.
And last night a flat in Gaza city owned by Mr Alagha was destroyed by air strikes, wiping out precious savings and leaving him “devastated”.
Mr Alagha said the Irish authorities “used to call more frequently” but are getting in touch less.
“It feels like they are just getting bored with us now and that nothing is going to happen.”
He added: “Either this war will end or, God forbid, I will die before it does, but it just doesn’t feel like we are going to be helped.”
In a joint statement on behalf of the Irish embassy and the Irish Department of Foreign Affairs, a spokesman said: “The Department of Foreign Affairs continues to work with Irish citizens in Gaza, and with the relevant authorities, to support them to depart from Gaza as soon as that becomes possible.
“We remain in daily contact with Irish citizens in Gaza.
“As with all consular cases, we do not comment on the details of individual cases.”
