National Disaster Management Agency spokesman Ahmad Kamal today says rescue crews are working round the clock to rescue people and ensure the provision of food and other supplies to flood-affected persons.
He says the floods entered the southern Sindh province yesterday, making thousands of people homeless.
Heavy monsoon floods, which began September 3 in Kashmir, have so far killed 523 people and affected 2 million in Pakistan and Indian-controlled Kashmir.
Of those, 200 died in the India-controlled part of the Himalayan region, 64 in Pakistani-controlled Kashmir, while 246 people perished across Pakistan.
