IDF is tweeting about war crimes. Furthermore. This was a building that is for residents of Gaza, the Associated Press, Al-Jazeera TV and other local news outlets.

The Israeli military has a history of targeting civilian structures of no military value and without any Hamas presence and later claiming that Hamas was using the building as a military base. Human Rights Watch documented some prior examples in part of this report:

After providing advance warning to civilians & time to evacuate, IDF fighter jets struck a multi-story building containing Hamas military intelligence assets. The building contained civilian media offices, which Hamas hides behind and deliberately uses as human shields.
