Israeli police arrested a 21-year-old resident of East Jerusalem on Sunday on suspicion of posting content on social media that incited against Israel and expressed support for terrorist organizations and individuals. The suspect, from the Sur Bahir neighborhood, was detained following an investigation into several videos he allegedly published online.

Authorities said the material included statements that were deemed to incite hostility toward Israel and showed identification with terrorist groups and terrorists. After the arrest, the individual was brought before a court on Monday, which approved an extension of his remand until Wednesday at the request of the police.

The investigation remains ongoing as law enforcement continues to review the suspect’s online activity. No further details have been released regarding the specific terrorist groups implicated or the nature of the videos posted.
