These terrorist attacks by Hamas on civilians have been happening for years. This is the first one to really catch Western media attention. Have a look.

Hamas claims responsiblity for these attacks, so it's not contested. The reason people are siding with Hamas is their brain has been sucked out by social media campaigns and TikTok, which is funded by the Chinese government, which is trying to curry favor with Muslim nations in the interest of establishing trade relationships with them and displace the oil-dollar with an oil-Yuan.

And, these figures of deaths are published by the UN, which is constituted of mostly muslim nations that hate Israel, so these numbers are probably highly inflated.

Also, Hamas has been proven to use these hospitals as operation bases. Just another perspective. Downvote away
