A suspected leak of classified Gaza documents involving an aide to Prime Minister Benjamin Netanyahu has jolted Israeli politics and outraged the families of hostages held by Hamas who have been pushing for a deal to get their loved ones home.

Details of the case have been trickling out only slowly because of a gag order.

But a court ruling partially lifting the order has provided an initial glimpse of the case which the court said had compromised security sources and may have harmed Israel’s war effort.

On Friday, the magistrates’ court confirmed that a number of suspects had been arrested as part of the probe into a suspected “security breach caused by the illegal provision of classified information.”

Netanyahu has denied any wrongdoing by his office staffers and said in a statement on Saturday that he was only made aware of the leaked document by the media. The suspects could not be reached for comment.

Details from the document in question were published by the German Bild newspaper on Sept. 6, according to Israeli newspaper Haaretz, one of the media outlets that had appealed the court to lift the gag order.

The article, labeled as an exclusive, purportedly outlined the negotiation strategy of Hamas, the Palestinian Islamist terrorist group which Israel has been fighting in Gaza for more than a year.

Around that time, the United States, Qatar and Egypt were mediating ceasefire talks between Israel and Hamas, that were to include a deal to release hostages held in Gaza.

But the talks faltered with Israel and Hamas trading blame for the deadlock. The article in question largely corresponded with Netanyahu’s allegations against Hamas over the impasse.

It was published days after six Israeli hostages were found executed in a Hamas tunnel in southern Gaza. Their killing sparked mass protests in Israel and outraged hostage families, who accused Netanyahu of torpedoing the ceasefire talks for political reasons.

On Saturday, some of the families joined the Israeli journalists’ appeal to lift the gag order.

“These people have been living on a roller coaster of rumors and half-truths,” said their lawyer, Dana Pugach.

“For the last year they have been waiting to hear any intelligence or any information about negotiations for the release of those hostages. If some of that information had been stolen from army sources then we think that the families have the right to learn about any relevant detail,” she added.

In another session on Sunday about the investigation by the Shin Bet domestic security service, police and the military, the court ordered one suspect be released, while keeping others in remand, according to Israeli Channel 13 News.

Asked about the investigation, Bild said that it does not comment on its sources. “The authenticity of the document known to us was confirmed by the IDF (Israel Defence Forces) immediately after publication,” it said.
