We can account for all the materials that can go into those projects.
Reuters fails to provide readers with any context for Israeli concerns by, for example, reporting on documented cases of Hamas stealing food and blankets and cement and other construction materials from the UN in the past.
We have little doubt that Palestinians are facing hardship as a result of property damage sustained during the Gaza war. A genuine and unbiased news story however, would balance an interview with a UN official sympathetic to the Palestinians with countervailing testimony from the Israeli perspective so as to fully inform its readers and enable them to draw their own conclusions as to who ultimately, is accountable for that hardship.
The alternative, manufactured by Reuters, is simply propaganda intended to play on emotions and lead the reader to a preordained verdict -- with Israel the guilty party.
