NEW DELHI – Rescuers worked in rain Thursday to dig through a remote village in western India where at least 21 people died as a landslide swept away scores of houses, possibly trapping many more people under debris, officials said. They had already worked through the night using floodlights mounted on jeeps and earthmoving vehicles to pull seven injured people out of the mud and twisted wreckage, Vitthal Banot, a disaster management official, said Thursday. They were taken to a nearby government-run hospital; their injuries were not life-threatening.
