The organisation said it was unable to secure basic assurances regarding the use and protection of that information. "Despite repeated efforts, it became evident that we were unable to build engagement with Israeli authorities on the concrete assurances required," MSF said.

The charity added that it sought guarantees that staff details would be used only for administrative purposes and would not place employees at risk.

MSF said those assurances were not provided and that it therefore "concluded that we will not share staff information in the current circumstances".
