Palestinian-Jordanian mountaineer Mostafa Salameh has climbed Mount Everest carrying handwritten letters from children in Gaza, in a symbolic mission to draw global attention to the hardships the territory's youngest residents have endured. Salameh, a noted high-altitude climber, undertook the ascent of the world's tallest peak as a deliberate act of advocacy, using the letters as a human testament to the crisis facing Gaza's civilian population. The gesture is intended to amplify the voices of children largely cut off from the international community amid ongoing conflict.
