At least 300 people were rescued Thursday after a powerful cloudburst triggered floods and landslides, but the operation was halted overnight. Officials said many missing people were believed to have been washed away.

Dozens of people are missing in both countries, while rescuers in Pakistan have evacuated 1,300 tourists trapped by flash flooding and landslides. Meanwhile, a helicopter carrying relief supplies has crashed in bad weather.

Sudden floods triggered by heavy rains have killed more than 200 people across parts of Pakistan, India-administered Kashmir and Nepal, authorities have said, as scores of people remain missing.
