Over 350 people have died in a 72 hour period in Pakistan due to monsoon flooding, Pakistan's National Disaster Management Authority reported, bringing the total number of people killed to over 650 since June 26.

Officials say rescuers have 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.
