The first ambulance came in at speed, tyres squealing.
Inside, was a 10-year-old boy.
They rushed him to the emergency ward, but there was nothing they could do to save his life.
We saw other children being brought in - a little girl, maybe five years old, carried in a paramedic's arms.
An ambulance brings a child to Gaza's Shifa Hospital She looked absolutely terrified.
The doctors told us they treated a six-month-old baby for shrapnel wounds to the head.
We saw an 80-year-old woman, clearly very frail and confused and clearly seriously injured.
"Gaza is living in a disaster situation," said Dr Sobhi Skaik at Shifa Hospital.
"Again the war is coming to kill and kill and kill.
"Today is the 33rd day of this massacre in Gaza. This is inhuman and it has to be stopped."
Dr Sobhu Skaik tends to an injured 80-year-old woman He said they need basic supplies now - surgical instruments, drugs, medication, and expertise - specifically vascular, orthopaedic and neurosurgeons.
One of the ambulances pulling up outside had blast damage to the windscreen and a bullet hole in the side.
Six medics have been killed in Gaza so far.
Paramedic Ahmed Abu-Ali said: "We feel we are targeted in any minute.
"All medical teams are now afraid they are targeted, it's very hard now.
"We wake up every day and we don't know if we are coming back to our homes or not."
We saw outgoing rockets too.
Although Hamas has not admitted firing any rockets since the ceasefire ended, Islamic Jihad and other smaller militant groups have said they fired on Israel.
But Israel says Hamas violated the ceasefire, and therefore Hamas is responsible for any resulting harm to the residents Gaza, who, it says, are being used as human shields.
But it's difficult to explain that argument to a parent carrying their child into the emergency ward.
