Israel's defense minister has signed an order that will keep a Jewish extremist in jail for six months without charges or trial.

The measure, known as administrative detention, usually sees Palestinian prisoners jailed for months or years without trial.

This is the first time Israel placed an Israeli under administrative detention since it launched a crackdown on Jewish militants following a pair of deadly attacks last week.

Defense Minister Moshe Yaalon's office said in a statement late Tuesday that Mordechai Meyer was arrested in connection with "violent activities and recent terror attacks."

Last week, suspected Jewish extremists torched a West Bank home, killing a Palestinian toddler and severely wounding his family a day after an anti-gay ultra-Orthodox man stabbed revelers at Jerusalem's Gay Pride parade, killing a 16-year-old girl.
