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.

ISLAMABAD (Reuters) -Nearly 200 people were killed in torrential rains in northwest Pakistan over the past 24 hours, with bad weather also bringing down a rescue helicopter, local officials said on Friday.

Rescuers recovered dozens more bodies from the rubble of collapsed homes in a northwestern district of Pakistan, bringing the death toll to at least 274, as authorities defended their response to the flooding and said they did not need any foreign help at this point.
