It looks like they denied knowing there was media housed there prior to the strike.
Israeli strike planners were reportedly unaware that the building housed foreign media outlets. At 1:40 P.M., the Shin Bet and the IDF started dialing and texting civilians, including journalists, known to be in the building, forewarning them to evacuate before an imminent strike. Shortly afterwards, two or three missiles hit the top of the site as part of Israel’s roof knocking warning system. The building’s owner contacted Israeli officials to get the strike called off, while journalists responded by alerting the IDF that journalists required more time to move their equipment out of the building. Once alerted, Israel’s military intelligence replied that it has no information regarding the presence of foreign media in the al-Jalaa tower. After discussing the new information for an hour Israeli military authorities decided to proceed with the strike on the grounds that, in their view, Hamas was using the presence of journalists as a human shield.
It looks like they changed the story about what the building housed.
It was later publicized that the IDF believed that a Hamas intelligence unit which operated a number of advanced electronic warfare devices was based in the building with the mission of interfering with the operation of Israeli smart bombs by disrupting their GPS reception.[21][22] On 1 June, Israel said it had provided intelligence to the U.S. government but said that it would not make the information public.[23] On 7 June, Israeli ambassador to the US and representative to the UN Gilad Erdan told top Associated Press executives that Hamas had been developing a system to electronically jam Israel’s Iron Dome defenses inside the building.[24]
