IDF is currently destroying the remaining high rise buildings still standing in Gaza City (there are still structure standing) because they are being used as strategic structures by Hamas to monitor & attack the IDF. These buildings will be booby-trapped so clearing them manually will put soldiers in danger which no army voluntarily does when there is another option. They’re also used as sniper positions.
Throughout the war, the IDF has published where they’re going to attack and have an early warning system in place. Thousands of leaflets have been dropped this morning warning those still in Gaza where they’re will be targeting. The maps show a general area for operations and advise where people should go to. This is standard.
It would, indeed, be better not to warn Hamas of imminent targets but casualty numbers would be far higher if they didn’t. Thought the entire war, Hamas has known where IDF was going to operate next. That’s why they can booby trap buildings and move the hostages around.
In response to the IDF’s latest warnings, Hamas have been telling the people to stay put as they’re the last line of defence & are vital to the success of the war. Paraphrasing as I can’t remember the exact wording, but that’s the list of it. Go nowhere as we need our shields. They’ve also undermined evacuation orders by saying they’re just going to kill everyone when they move etc which isn’t the case.
