A Palestinian man threw a large rock at a young Israeli boy playing in a spring in the West Bank city of Hebron, knocking him unconscious, according to the army.

The 12-year-old boy on Saturday then fell into Abraham’s Well spring, located in the flashpoint city’s Jewish enclave. His friends pulled him out of the water and called for help. He was taken to Hadassah Hospital Ein Kerem in Jerusalem, where he required 10 stitches in his scalp

The IDF spokesman said a Palestinian man had thrown the rock and security forces were searching the area for suspects.

“Such violence is nothing less than terror,” he said.

Footage from an army security camera appears to show the man hurling the rock into the spring from above before running away. The video is being shared on social media.
