I think it is more likely that the Israeli government would have abused Gaza's wireless emergency alert system to send a link to a live stream to every cell phone. AFAIK, emergency alert systems are limited to text messages but smartphones will recognise URLs to allow users to tap to open them.

But a user would have needed to actively tap on the link to open the stream.

Yeah my initial thought would be it sends something like a Amber alert with messages -- a bit stretch of the truth
