They've been saying stuff like this for years. They say it every day, every week, on channels across the Arab world. There's hundreds and hundreds of videos just like this one on the MEMRI website. This is a systematic campaign of extermination against Jews. And it's not just Hamas (who are, erm, an Iranian outfit who absolutely, positively do not give a toss about real Palestinians, leaving them to die, using them as human shields and promoting them as suicide terrorists) who do this. This is on Saudi, Egyptian, Iranian, Yemeni, etc etc, television. It's all over the place.
Also, they don't just target Israel here - these people (and those like them in other Arab countries, not just in the disputed territories) routinely deny or praise the Holocaust and demonise Jews for being Jews. All Jews. Even those that have never been to Israel. They variously demand that Jews be driven out of the Middle East or killed. Some others go further and say that all Jews in the world should be murdered.
If I had said some of the same stuff about Muslims as Islamists say about Jews on Arab TV, I'd expect to be in jail.
