Jerusalem (AFP) - Israel Sunday arrested several suspects believed to be linked to the deadly firebombing of a Palestinian home and placed two more alleged Jewish extremists in detention without trial.
The moves came as calls mounted for a crackdown in the wake of the July 31 arson attack in the West Bank village of Duma, that killed 18-month-old Ali Saad Dawabsha and his father Saad.
While the toddler died on the day of the attack, his father succumbed to his injuries on Saturday and was buried in an emotional ceremony attended by thousands, some of whom could be heard calling for revenge.
Some hurled rocks at Israeli border police, who responded with tear gas.
Veteran Israeli security commentator Yossi Melman wrote Sunday in the Maariv daily that Israel's actions to quell Jewish violence against Palestinians, "do not attest to great determination."
"We should not delude ourselves that the Palestinians will accept more terror acts by settlers and will be willing to suffer and not react," he said
On Sunday the army said a group of Palestinians attacked a 26-year-old Israeli motorist at a West Bank petrol station, stabbing him in the shoulder and lightly wounding him.
Troops at the scene shot one suspect who died shortly afterwards of a leg wound, according to police, and the army said that troops were searching for up to three accomplices.
Ali Dawabsha's mother and four-year-old brother were also critically wounded in the firebombing, which occurred only hours after a stabbing attack at a Jerusalem Gay Pride march that killed a 16-year-old girl and wounded five other people.
While the attacks were not related, both have led to criticism of Israel's government and security forces, who have been accused of failing to properly address Jewish extremism.
Prime Minister Benjamin Netanyahu has pledged to tackle the problem and labelled the firebombing "terrorism" -- a word usually reserved by Israelis for violence by Palestinians.
The suspects arrested Sunday were swept up in raids on wildcat Jewish settlement outposts in the occupied West Bank as part of "the investigation into the events that occurred in Duma," police said in a statement.
It did not identify them or say how many were arrested.
- Administrative detention -
The international community regards all Jewish settlements in the West Bank as illegal but the Israeli government makes a distinction between those it has authorised and those it has not.
The wildcat outposts, often little more than a few caravans, are notorious for housing young hardliners, referred to in Israel as hilltop youth.
Separately, the defence ministry said two more alleged Jewish extremists were placed in what is known as administrative detention, which allows suspects to be held without charge indefinitely.
A third alleged extremist was put in administrative detention several days ago. The measure is usually used for Palestinians.
One of those interned 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 a string of nationalist hate crimes.
Ettinger's grandfather Meir Kahane founded Kach, a racist movement that wanted to chase Arabs from Israel. Kahane was assassinated in New York in 1990.
The three under administrative detention have not been directly accused of the firebombing.
Defence Minister Moshe Yaalon said in a statement the two interned on Sunday were suspected of links to a "Jewish extremist organisation".
Administrative detention is intended to allow authorities to hold suspects while continuing to gather evidence, with the aim of preventing further attacks in the meantime. It also allows authorities to avoid divulging sensitive intelligence in court proceedings.
- Churches threatened -
The Dawabsha family's small brick and cement home was gutted by the fire, and a Jewish Star of David was spray-painted on a wall along with the words "revenge" and "long live the Messiah".
On Monday, the Palestinians submitted a request to the ICC to probe the firebombing and "settler terrorism".
Amid the concerns over Jewish extremism, the head of far-right group Lehava, Benzi Gopstein, last week was reported to have publicly called for the torching of churches.
A Catholic official told AFP on Sunday that an assembly of churches in the region had filed a complaint with police over the reported comments.
In June, part of a shrine in northern Israel where Christians believe Jesus carried out the miracle of loaves and fishes was torched. Three alleged extremists have been charged in connection with the arson.
