Mark Regev, who is a senior adviser to Israeli Prime Minister Benjamin Netanyahu, has told the BBC News Channel he is sure "more and more material" from what he says is Hamas's subterranean network under the Al-Shifa hospital will be shared.

It comes after the Israel Defense Forces published footage from inside the hospital, which purported to show Hamas weapons and technological assets found during its day-long operation at the medical facility in Gaza City.

Regev went on to tell the BBC's Newshour programme on the World Service that mounting a military operation at the hospital was justified:

Quote Message: International law specifically says that the minute your enemy uses a humanitarian site like a hospital for its military machine then you can target that site… It doesn’t mean you do so lightly or irresponsibly but under international law it loses its immunity."

Hamas has denied Israeli claims that it has a command-and-control centre beneath the Al-Shifa hospital and on Wednesday night described such allegations as "lies and cheap propaganda".
