Rayan Tamer Anwar Houshyeh was killed by a sniper earlier this week in the occupied West Bank town of al-Yamoun after he peeked over a wall during an Israeli military incursion, Al Jazeera reports, citing a child rights group.

The 13-year-old “looked over a stone wall in an alley near the Omar Ibn Al-Khattab Mosque to observe nearby Israeli forces” and was shot by the sniper from a distance of 50 to 60 metres (164 to 196 feet), said Defence for Children International — Palestine (DCI-P).

He was struck by bullets in the neck, abdomen, and thigh, the group said.

“Israeli soldiers entered Rayan’s hometown, killed him without a second thought, and no one will be held responsible. This is Palestinian childhood today,” DCI-P’s Ayed Abu Eqtaish said in a statement.

Rayan’s killing marks the 30th Palestinian child killed by Israeli forces in the occupied West Bank so far this year, DCI-P added.
