At Telegram channels. Subscribe to the top channels for both and then use your own discretion. Note: You need to use translate tool in Telegram as they use local languages.
If you need some hints for the name of the channels (the ones I sub to):
For the Israeli: search for kod[twice]group about 148k subscribers.
For Gaza: search for G××× Now. about 1.5M subscribers.
Need to be careful. There are some fake channels having similar names to those. So you need to double check the number of subscriptions.
