A Palestinian stands in his badly damaged house as the ruins of houses are seen in the east of Gaza City

A Palestinian stands in his badly damaged house as the ruins of houses, which witnesses said were destroyed during the seven-week Israeli offensive, are seen in the east of Gaza City August 31, 2014. Fifty days of war in one of the most densely populated parts of the world have left swathes of Gaza in ruins. With the economy reeling under an Israeli-Egyptian blockade, the enclave now faces an almost impossible task of rebuilding. Picture taken August 31, 2014.
