Of course you don't believe it, because it's nothing more than the figment of someones imagination. You and I both know that if you don't drink water in 3/4 days you die. Now looking at how hot it is in that part of the world it's probably more like a day or two max. As for the UN, you do realise this is extremely corrupt (do your own research on this).
Let's face facts here, some of the people in this thread are Anti-semetic terrorist sympathisers, even denying that the Al-shifa hospital was used as a terrorist base, well here's the video evidence and video of some of the Israeli hostages been help there. (not to mention the two dead hostages found outside the hospital area last week) - just to about 4 minutes in if you want to get straight to the hostages.
Then there's the moron trying to defend the bias BBC as claiming there wasn't a tunnel under the hospital, well here's some drone footage of it:
Then there's the weapons found inside the hospital:
No matter what information is available to these anti-semite terrorist sympathisers, they are entrenched in their views and will only post anti-semite shit, rather than accept that these Hamas murderous scum murdered innocent babies/children/men and women. You don't hear them asking or marching for Hamas to release the hostages and for the ones that did the murdering to hand themselves in to face justice. No they are too busy trying to find anti-semtic crap to post.
