An extremist Salafi organization known as Dawlat al-Islam has distributed pamphlets in Hebron claiming responsibility for the feared kidnapping of the three Israeli teens.

Israel security services are investigating the validity of the claim.

A self-described Al-Qaida offshoot, Dawlat al-Islam is linked to ISIS, the Sunni militant organization behind this week's Iraq insurgency.

Last November, Israeli commandos killed three members of a Salafi terror cell in the South Hebron Hills village of Kfar Yatta. The three were planning an attack on Israel, and pistols and explosive devices were found at the site of the operation.
