As grugq keeps saying, the advancement in deepfakes will not make a huge change in fake news as long as cheapfakes (reusing images from different context) is quick and effective. This and the photos of people hoarding gas in the US seem to confirm it once more.

That's a good point I hadn't heard before, perhaps it would be relatively straight forward to build tools that detect this kind of thing? E.g., as per the article, an image/video tagged as being in 'Syria' later being tagged in 'Gaza' could be flagged up for human review.

It depends on what you mean by that. Many Palestinians would consider all of Israel to be occupied Palestine. What I think what you mean to ask is if they are firing on illegal settlements. No, those are in the West Bank. They are mainly firing at Ashdod, Ashkelon, Beersheeva and Tel Aviv which are all north and east of Gaza.

Could their rockets even reach those areas even if they tried, even if the Iron Dome wasn't stopping most of them from getting through? I'm not familiar with their capability/reach.

They are unguided munitions. They're an accelerated cannon ball and even then they don't seem to put much effort into aiming them at all.

It is a futile exercise to try to hit anything with these rockets. They will occasionally hit something by pure accident.

Rockets from Gaza already reached Jerusalem and the sorrounding area, so yeah they can.
