Now, Israel and Hamas have agreed a several three-day pauses in fighting to allow the vaccinations of more than 600,000 children in Gaza against polio. It's been confirmed a baby has contracted the disease, the first in the Palestinian territory for a quarter of a century. Lucy Williamson has the very latest.

Born a month before the Gaza war began, Abdul Rahman has played a role in pausing it, something world leaders have struggled to do. Earlier this month, Abdul Rahman was diagnosed with polio, the first case in Gaza for 25 years. The family, nine children in all, live in a camp in central Gaza, displaced multiple times from their home in the north. The constant moving disrupted his vaccinations. His mother says others in the camp are afraid and stop their children playing with them.

The virus stopped his progress. He stopped sitting, stopped walking, stopped crawling, and stopped moving. I want him to be treated. He wants to live and walk like other children.

Abdel Rahman's diagnosis has raised fresh alarm over conditions in Gaza's camps. The phased pause in fighting will allow medics to vaccinate more than half a million children in stages across the territory. But the conditions that caused this crisis are worsening, say aid organizations, and their solutions are not straightforward.

Due to the insecurity, the damage, the road infrastructure, and population displacement, but also based on our experience with this campaigns globally and worldwide, the three days might not be enough to achieve adequate vaccination.

Israel's Prime Minister was clear that this was not a ceasefire. The war has so far been resistant to both diplomacy and disease. But preventing another layer of tragedy is seen as one small victory, what the EU's foreign policy chief called a drop of hope in a sea of despair. Lucy Williamson, BBC News, Janine.
