A foundation created with backing from the Trump administration to establish a new system for aid to flow into the Gaza Strip said on Wednesday that it had reached agreements with Israel to begin operations in the enclave before the end of the month. It also suggested that Israel had agreed to allow aid into Gaza as the foundation is setting up its operations.

The Gaza Humanitarian Foundation is meant to create an alternative aid system for the war-torn enclave and to end Israel’s two-month blockade on food and fuel deliveries. Israeli officials say the measure was imposed to pressure Hamas, by reducing the militant group’s ability to access and profit from food and fuel meant for civilians.

The blockade has raised alarms from international organizations about the risk of famine and also from some Israeli military officials who said privately that Gazans will face widespread starvation unless aid deliveries are restored within weeks.

But some other aid groups have already raised doubts about the Gaza Humanitarian Foundation’s approach and the plan’s feasibility.

The foundation’s general plan, according to two Israeli officials and a U.N. diplomat, had been to establish a handful of distribution zones that would each serve food to several hundred thousand Palestinians. This had led to concerns that vulnerable civilians would be forced to walk longer distances to get to the few distribution hubs, making it harder to get food to those who need it most.

In a statement on Wednesday, the foundation for the first time gave an indication of when it would start and said that it had secured several key agreements with Israeli officials. These agreements include allowing aid to flow into Gaza while the foundation sets up the distribution sites, letting the foundation establish sites in more places in the enclave, and creating alternative arrangements for those who cannot reach its locations.
