Thanks for the reply. So to sum up my own understanding of what you sent - neither Israel nro Levy has officially denied entry of aid, though Kearns claims that the UK gov / Egyptian gov / UN all told her that the Israeli gov did not want aid deliveries coming in on Saturdays (she makes no mention of aid coming in any other day of the week).
So she is claiming that the crossing is closed on Saturdays because Israel requested no aid to come on Saturdays, whereas Levy claimed that the crossing was closed Saturday at the request of the UN. That disagreement is about the cause for a crossing being closed on a Saturday, and does not mean that aid is being blocked in general from entry. Israel has suspended Levy, but has not officially disagreed with his statement that Israel is letting as much aid in as can be sent.
