A Palestinian boy killed by Israeli occupation forces during protests in March was fatally injured by an explosive grenade, an investigation by the human rights group Al-Haq has found.

Adham Nidal Amara, 17, was directly injured in his face, killing him, as he took part in the rallies marking the one-year anniversary of the Great March of Return protests east of Gaza City on 30 March.

Two other teens, Tamer Hisham Abu al-Khair, 19, and Bilal Mahmoud Shaban Najjar, 16, were shot and killed by Israeli forces while protesting in Gaza that day. A fourth person, Faris Yusif Faris Abu Hijris, 26, succumbed to wounds sustained during the protests two days later.
