The IDF revealed on Friday, what it described as intelligence showing a Hamas command center located under a the Shifa Hospital in Gaza City. In a briefing, Rear Admiral Daniel Hagari told members of the foreign press corps that there are areas in the hospitals that are used by Hamas to direct its military operations.
If only they bordered a large body of water that might have shells
There aren’t enough shells in the whole middle east, let alone Gaza to make the required amount of cement.
It depends on what they are actually doing with the cement.
Most of the tunnels in the news seem to be using regular building materials which is likely stripped from older homes or never makes it to new homes
You just reduced the required amount of shells to maybe just the whole of the middle east and even that is questionable. Hamas has access to enough beach to fix some cracks and maybe even piece together one wall out of very large pieces of a building that fit together very well over 20 years but not much else. The amount of seashells you need for a decent amount of cement is colossal, for anything serious you need a limestone mine.
Not to mention the facilities to produce the cement that would give off massive amounts of heat and smoke.
And yet we have images and video of the actual tunnels. So perhaps they found a genie and that made them cement. Or the more likely way is that its smuggled in
I have seen videos and images of those tunnels as well. One tunnel, that has images of it seems to have broken building pieces as reinforcement and every other I have seen is just been dirt and stone. Nothing like the illustration Israel published, definitely no red barrel room, or even any room, just tunnels.
Then you should go check it out for yourself if you don’t belive them.
