Rescuers pulled out survivors caked in dark brown mud and helicopters lifted stranded people to safety Friday as Nepal and China raced to respond to catastrophic flash floods that killed nearly 600 people and left almost 2,500 missing. More than 3,700 people have been rescued in Nepal so far. Meanwhile, the number of people who were unaccounted for in the country nearly doubled to 1,924 as more local residents were added to the tally. China's state media said 554 people were missing on the Chinese side. Hundreds of the missing are foreigners in the area to work, trek or make a pilgrimage to a sacred peak. #nepal #china #mudslide
