Fascinating (but sad) to watch a slow motion mass casualty event in play in #South #Korea at the World Scout Jamboree. A local television station set up and has been livestreaming, and you see a constant parade of ambulances. The US and UK have already retreated and withdrawn from the event. Already 700+ people treated for heat illness when I checked last night. #heatwave #MCI https://www.youtube.com/watch?v=xEtWRoekNOA
