(Andrew Friedman/TPS) Shin Bet and Israel Police said Wednesday that an Israeli citizen, currently residing in the Palestinian-majority city of Jaljulia, is providing support for ISIS and planning to join the terror group.

The man, who was a minor at the time of his alleged offense, was detained after security officials received detailed information indicating that he was planning to go to Syria.

Investigators said the man had become increasingly religious recently, while also maintaining connections with ISIS fighters in Syria. The suspect told individuals in Syria that he wanted to join the organization.

Investigators also found that the suspect possessed illegal weapons, including Uzi and Glock guns. He also photographed himself firing the weapons into the air. Investigators also found a large number of photographs allegedly proving his support for ISIS and his weapons business.

Last month, three residents of Taybe were arrested and admitted during interrogation that they supported ISIS, planned to go to Syria and dug weapons-smuggling tunnels underneath the West Bank security fence.

The Shin Bet said in a statement that the security service views support for ISIS by Israeli citizens, and Israeli citizens who are in Syria, as a serious security threat. They said that all available means will be used to finding [these individuals] and thwarting the threat they pose, including charging them with terrorism and other security-related offenses.
