Qatar and France have brokered a deal with Israel and the Palestinian fighter group Hamas to deliver urgent medication to some 45 Israeli hostages held by the group in Gaza in return for humanitarian and medical aid for the most vulnerable civilians, Reuters reports.

The two countries said the aid would leave Qatar for Egypt today before being taken across the Rafah border crossing.

Qatari foreign ministry spokesperson Majed al-Ansari said in a statement the deal would mean “medicine along with other humanitarian aid is to be delivered to civilians in the Gaza Strip, in the most affected and vulnerable areas, in exchange for delivering medication needed for Israeli captives in Gaza.”

He did not give details on how much aid or what aid would be delivered to civilians.

Earlier, Philippe Lalliot, head of France’s foreign ministry crisis centre which organises aid efforts, said negotiations had been going on for weeks and the initial idea had come from the families of some of the Israeli hostages.

Specific medical packages for several months, which were put together in France, would be delivered to each of the 45 hostages. The International Committee of the Red Cross will coordinate on the ground.

France still has three nationals held in Gaza, but none of them are in urgent need of medication, Lalliot said.
