Four years ago, Israeli forces and Hamas militants fought a 50-day war. The fighting caused heavy damage to many buildings, roads and other infrastructure in the Gaza Strip. Now, Israel fears a humanitarian disaster along its border. The country is appealing to the world to provide support for a series of development projects in Gaza. Qatar has become an unlikely partner in the Israeli effort. The wealthy Gulf state has offered to donate money and is urging other nations to do so. But, it remains unclear whether the rest of the international community is ready to help. Donors have noted some successes in rebuilding Gaza since the 2014 war. But they say Israeli government officials are still too slow in approving projects. And they say Israel’s blockade of Hamas-ruled Gaza is working against the goal of developing the territory’s economy. The World Bank has helped direct the rebuilding effort. The aid organization said, “Israel now realizes the growing humanitarian crisis in Gaza and its impact on the population.”
