In Washington, D.C., activists are delivering a petition calling for an investigation into the death of 16-year-old Palestinian American Mahmoud Shaalan, who was shot and killed by Israeli soldiers at a checkpoint near the Jewish-only Beit El settlement in the Israeli-occupied West Bank in February. Witnesses said that the soldiers continued shooting Shaalan even after he had fallen to the ground, and then prevented an ambulance from taking him to the hospital. Israeli soldiers say Shaalan tried to attack them with a knife.
