The United States will not share any Israeli intelligence or elaborate on its own intelligence assessment that Hamas used Gaza’s Al-Shifa hospital as a command centre and possibly as a storage facility, White House spokesman John Kirby has said.

The United States is confident in an assessment from its own intelligence agencies on Hamas activities in the Gaza facility, Reuters quoted Kirby as saying. He has refused to elaborate or provide details over the past several days.

The Biden administration has not declassified the sources of the US intelligence “because some of those same channels are being used to monitor the status of hostages,” a knowledgeable source said.

The intelligence “is definitive”, said the source, and includes communications intercepts of Hamas fighters. The intercepts were first reported on Wednesday by the Wall Street Journal.
