Jordanian security forces arrested several youths who are suspected of attacking Israeli internet sites as part of the large scale cyber attack on Israel declared by the group called Anonymous.

In response, Anonymous threatened to attack Jordanian internet sites. The group demanded the activists' immediate release.

A Facebook group called "The Third Intifada – Jordan" boasted that 100,000 Israeli internet sites had been disabled.

"Today we invade their internet sites and their electronic fortresses, and tomorrow we will attack them in their homes, which were established upon our land and which robbed us of our rights," the group wrote.
