The Zionist police arrested several suspects Sunday in raids linked to the deadly firebombing of a Palestinian home and placed two more alleged Jewish extremists in a controversial form of detention without trial, officials said.

The authorities\' moves came as calls mounted for a crackdown on Jewish extremism in the wake of the July 31 arson attack in the West Bank village of Duma that killed an 18-month-old child and his father.

The child\'s mother and four-year-old brother were also critically wounded in the firebombing.

Zionist Prime Minister Benjamin Netanyahu has pledged to tackle the problem and labeled the firebombing \"terrorism\".

The suspects arrested on Sunday were detained in raids on wildcat Jewish settlement outposts in the occupied West Bank as part of \"the investigation into the events that occurred in Duma,\" occupation police said in a statement.

It did not give the number of arrests or the suspects\' identities.

The international community regards all Jewish settlements in the West Bank as illegal but the Zionist government makes a distinction between those it has authorized and those it has not.

Separately, the defense ministry said two more alleged Jewish extremists were placed in what is known as administrative detention, which allows suspects to be held without charge for six-month intervals that can be renewed indefinitely.

A third alleged extremist was put in administrative detention several days ago. The measure is usually used for Palestinians.

One of those placed under the measure on Sunday was Meir Ettinger, a 23-year-old accused of being a key figure in a loose band of youths suspected to be behind \"price-tag\" attacks -- the term used to refer to nationalist hate crimes.

Ettinger\'s grandfather Meir Kahane founded Kach, a racist movement that wanted to chase Arabs from the occupied territories. Kahane was assassinated in New York in 1990.
