A trial for a mass environmental injury case is starting more than two years after a U.S. military fuel tank facility under ground poisoned thousands of people when it leaked jet fuel into Pearl Harbor's drinking water. The 17 plaintiffs represent more than 7,500 others, including service members. Lawyers for the plaintiffs argue Navy officials knew there was fuel in the water and failed to warn people not to drink it, even while telling residents the water was safe. Attorneys for the U.S. government dispute whether the plaintiffs were exposed to jet fuel at levels high enough to cause their alleged health issues.

Cambodia has held a funeral for 20 soldiers who died at an army base in a huge explosion of stored munitions that also wounded several others and damaged nearby houses. There has been no public explanation of what caused the Saturday afternoon blast at the base in Kompong Speu province, though there were no suggestions it was caused deliberately. Defense Minister Tea Seiha, representing Prime Minister Hun Manet, presided over the Buddhist funeral ceremony on Sunday, which was attended by relatives of the victims and fellow soldiers. Cambodian flags covered the wooden coffins.

Yemen’s Houthi rebels have claimed shooting down another of the U.S. military’s MQ-9 Reaper drones. They aired footage Saturday of parts that corresponded to known pieces of the unmanned aircraft. The Houthis said they shot down the Reaper with a surface-to-air missile. The U.S. military acknowledged to The Associated Press that “a U.S. Air Force MQ-9 drone crashed in Yemen.” It said an investigation is underway. The rebels have launched a renewed series of assaults this week after a relative lull in their pressure campaign over the Israel-Hamas war. The Houthis described the downing as happening Thursday over their stronghold in the country’s Saada province.
