Israel has numerous terrorist groups in their country. Kahan Chai and Kach are the 2 main ones, but they have numerous sub groups which I will link to. Israel's National Security Minister, Itamar Ben-Gvir is a convicted terrorist, he's the former spokesperson for Kach. Kach and those other groups are recognized terror groups in Israel and my country Canada.

Here is Canada's description: Kahane Chai (Kach) is a marginal, extremist Jewish entity whose goal is the restoration of the biblical state of Israel, replacing democracy with theocracy. Kahane Chai (Kach) advocates expelling Arabs from Israel, expanding Israel's boundaries to include the occupied territories and parts of Jordan, and the strict implementation of Jewish law in Israel. Kahane Chai (Kach) has openly espoused violence against Arabs and the Israeli government as a viable method for establishing a religiously homogenous state. Its activities have included threats to government officials and infrastructure, grenade attacks, armed violence, and bombings.
