During that IDF news conference, one of the claims Israel made was that it had a clip of Palestinian militants discussing a failed rocket launch.
This, the Israeli military claimed, proves that the blast at Gaza's Al Ahli hospital was caused by the Palestinian Islamic Jihad (PIJ) militant group.
The transcript of the conversation - as released by Israel - shows two people discussing the damage caused.
"They are are saying it belongs to PIJ," one says, to which the other replies: "It's from us?"
The original speaker goes on: "They shot it from the cemetery behind the hospital."
"What?!" the other responds, to which they are told: "They shot it coming from the cemetery behind the hospital, and it misfired and fell on them."
Spokesman Daniel Hagari said: "We have cross-checked this intercept with other intelligence sources to confirm its accuracy."
Our team at BBC Verify is investigating the explosion at the Al Ahli Arab hospital, which health officials in Gaza say killed hundreds of people.
Palestinian officials say it was caused by an Israeli air strike; the Israelis say it was caused by a rocket fired from inside Gaza.
We’ve been showing videos from last night and images of the aftermath taken this morning to weapons experts to try to verify what happened.
While there is no overall consensus, one said the fact that hospital buildings have not collapsed, some cars are undamaged and there is no visible deep crater suggests that this was not consistent with an Israeli air strike.
We have also showed a video with the apparent sound of the impact to these experts - one said he couldn’t tell whether this was an Israeli strike or a rocket fired from inside Gaza.
But the BBC has not been able to verify Israel's version, including who was talking in the clip, which you can listen to here.
Our Verify team is piecing together last night's events, including speaking to weapons experts - stay with us for updates.
