UN calls for investigation into mass graves uncovered at two Gaza hospitals raided by Israel

The United Nations called Tuesday for “a clear, transparent and credible investigation” of mass graves uncovered at two major hospitals in war-torn Gaza that were raided by Israeli troops. Credible investigators must have access to the sites, UN spokesman Stephane Dujarric told reporters, and added that more journalists need to be able to work safely in Gaza to report on the facts.
