Three Jewish minors were arrested on Sunday over their alleged involvement in a "serious terrorism case," the Shin Bet security agency said.
The investigation, headed by the Shin Bet and the Judea and Samaria District Police, has been placed under a broad gag order, preventing the release of any additional details.
The three were scheduled to be arraigned on Monday at the Rishon Lezion Magistrates' Court. Authorities are expected to ask the court to keep the suspects in custody pending the conclusion of the legal proceedings.
The defendants are being represented by right-wing legal aid group Honenu.
"It seems that the Shin Bet and the State Attorney's Office haven't learned any lessons from previous cases, nor are they heeding public criticism. They are still trying to use violent methods to coerce confessions from teenagers," Honenu attorney Adi Kedar said.
"In this case, too, a minor was denied a meeting with his attorney. We plan to file an urgent appeal to allow us to meet with the teens," he said.
Kedar was referring to the 2015 Duma arson investigation, in which several Jewish men, some of them minors, were indicted for the murders of three members of the Palestinian Dawabshe family.
The Central District Court ruled that confessions obtained under duress from the suspects were inadmissible.
Attorney Itamar Ben-Gvir, who represents another suspect in the latest case, echoed Kedar's criticism.
"Experience shows that the Shin Bet's Jewish Division uses aggressive and problematic methods to interrogate hilltop youths, which makes it impossible to get to the truth and at best yields false confessions," he said.
The Tag Meir ("Bright Tag") organization, which fights hate crimes, including the "price tag" vandalism phenomenon, issued a statement supporting law enforcement agencies.
"Tag Meir strengthens security forces in their efforts to bring Jewish terrorism suspects to justice," the group said in a statement.
"Tag Meir rejects the automatic attempt by Honenu to taint security forces' activities by claiming they employ undue force to coerce confessions from teenage suspects. The fact that teens are involved does not diminish the need to get to the truth in such cases," the statement said.
