Curled up in his father's lap, clinging to his chest, Hussein Mikdad cried his heart out. The 4-year-old kicked his doctor with his intact foot and pushed him away with the arm that was not in a cast. "My Dad! My Dad!" Hussein said. "Make him leave me alone!" With eyes tearing up in relief and pain, the father reassured his son and pulled him closer.

Hussein and his father, Hassan, are the only survivors of their family after an Israeli airstrike last month on their Beirut neighborhood. The strike killed 18 people, including his mother, three siblings and six relatives.
