Thirty aid agencies have condemned the lack of progress rebuilding Gaza, six months after the end of a devastating Israeli assault. The groups say reconstruction of tens of thousands of destroyed homes, schools and hospitals has been “woefully slow,” with 100,000 Palestinians still displaced. The agencies called on Israel to lift its naval blockade, which has barred needed construction materials from entering. Oxfam says it will take more than 100 years to rebuild Gaza if the Israeli blockade remains.
