Tel Aviv, August 5 (RHC)-- Israel has arrested and jailed a Jewish settler for six months without charges or trial. The detention comes as Israel attempts to crack down on Jewish extremism following a firebombing of a Palestinian home in the West Bank last week, which killed an 18-month-old baby.

The Israeli government has expanded the use of detention without trial to include Jewish Israeli citizens suspected of attacks against Palestinians. It also said authorities can use harsh interrogation methods against jailed Jewish extremists.

And Israeli authorities have also arrested Meir Ettinger, the grandson of Meir Kahane, for his "involvement and activities in extremist Jewish organizations."

Meir Kahane is considered the father of right-wing Jewish extremism. He founded Israel’s anti-Arab Kach political party, which called for the forced removal of all Palestinians. He was murdered on the streets of New York City in 1990.
