Hamas has over run some of Israel’s military bases. Entire families and car loads of Israeli civilians have been slaughtered in the most brutal surprise attack on the Sabbath when many Israelis were celebrating. Hostages have been taken.
A lot of the main points to come out so far are in the above link. The only thing missing are videos showing them shooting up civilians in communities that Hamas has overrun. Those are on telegram but most other sites will not touch them for obvious reasons. You can see some discussion of them here with out images but documenting where they happened.
Iran of course is saying they support this but strangely Hezbollah has not joined in. Makes me wonder if Hamas did not cook this all up on their own.
Edit: Images and Videos were circulating earlier which showed a number of Women being Paraded through Gaza some appearing to only be as Young as 10 and all having been Severely Beaten. I have seen one and it was enough.
