The Israel Defense Forces announced that a teenage Israeli boy who was reported missing on Friday has been found “murdered in a terrorist attack” in Gaza’s West Bank, after his disappearance set off a clash between Palestinians and Israelis.

The body of 14-year-old Binyamin Achimair was found near where he had been reported missing, and an investigation into his death is underway. The investigation is being carried out by Israel’s security agency Shin Bet.
