The Israeli-Hamas war lasted for 22 days, and in the wake of the ceasefire in the Gaza Strip, surviving Palestinians returned to homes crushed beyond repair and mourning of lost relatives. 13 Israelis and more than 1300 Palestinians were killed. An estimated 4000 buildings were destroyed. 50.000 Gazans were left homeless, and the areas where Israeli tanks and artillery poured in at the start of the ground war are devastated: Beit Lahiya, El Atatra and large sections of Jabaliya, as well as the outer Gaza City neighbourhoods of Zeitoun and Toufah. UN estimates it will cost several billion dollars to rebuild the Gaza Strip.
