In the early afternoon of 29 November last year, several Palestinian boys descended on to their street in the occupied West Bank, where they often played together.

Minutes later, two of them lay dead from gunshots fired by Israeli soldiers - Basil, 15, and eight-year-old Adam.

As part of an investigation into the conduct of Israel’s security forces in the West Bank, which has been under military occupation for more than half a century, the BBC has pieced together what happened on the day the two boys were killed.

Mobile phone and CCTV footage, information about the movements of Israel’s military, witness testimony and detailed investigation of the scene, including taking measurements, combine to reveal evidence suggesting serious human rights violations.
