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, Ednews reports via BBC.

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.

The evidence we found has prompted Ben Saul, UN special rapporteur on human rights and counter-terrorism, to say the death of Adam appears to be a "war crime".

Another legal expert, Dr Lawrence Hill-Cawthorne, described the use of lethal force as “indiscriminate”.

The Israel Defense Forces (IDF) said the circumstances of the deaths were “under review” but said “live fire is used only in order to remove immediate threats or for arrest purposes, following arrest protocols after exhausting other options”.

With violence having surged in the West Bank in the months since Hamas's attack on Israel from Gaza on 7 October, the BBC has also found evidence of Palestinian homes being vandalised with graffiti, Palestinian civilians threatened with weapons and told to leave the territory for neighbouring Jordan, and the possible mutilation of the body of a Palestinian gunman.
