Two California juveniles could face charges here and three teenagers are under house arrest in Israel following a hacker attack on the Pentagon's computer system and other U.S. and Israeli networks, the FBI says.

On Thursday, two 18-year-olds in Israel were placed under house arrest after being identified by a joint U.S.-Israeli investigation, the FBI's National Infrastructure Protection Center said.Their detention followed by one day the house arrest of an 18-year-old Israeli hacker who calls himself "The Analyzer." Identified by the Justice Department here as Ehud Tenebaum, he was questioned Thursday by a special Israeli police anti-hacker unit.

All three Israeli teenagers have admitted their involvement in the highly organized computer intrusions, the FBI said.
