A Palestinian paramedic who witnessed an incident in which 15 of his colleagues were killed in southern Gaza last month said he saw Israeli troops firing at emergency vehicles that were later found stained with blood. The Red Crescent and United Nations officials found the bodies of the aid workers buried in a mass grave in southern Gaza, accusing Israeli forces of killing them. The paramedic's account aligns with assertions made by officials from the Palestinian Red Crescent and the United Nations. The Israeli military is investigating the incident.
