Israeli settlers on Wednesday shot and killed 19-year-old Palestinian-American Nasrallah Abu Siyam as they attacked the Palestinian village of Mukhmas, east of Ramallah, in the occupied West Bank.

He and other residents had intervened to defend a Palestinian farmer under attack by a group of settlers, a witness told the Associated Press.

The Israeli army showed up and dispersed tear gas, sound grenades and live ammunition, the witness, Mukhmas resident Raed Abu Ali, told the AP.

Video circulating on social media appears to show the moment Abu Siyam was shot and his body being dragged away.
