UN aid workers say Pakistan's worst floods in living memory have affected more than 3 million people -- with a death toll from the devastating monsoon rains now topping 1,400 people.
Abdul Sami Malik says 1.3 million people have been severely affected by floods in the northwest with many people displaced and entire villages washed away in the northwest province of Khyber Pakhtunkhwa.
The International Red Cross and Red Crescent is providing relief aid. Islamist charities, some with suspected ties to militants, also have stepped in to provide help -- piling pressure on the government to show it can take control of the crisis.
"WHO is providing support for 200,000 people by sending medicine and medical equipment, but more medical support will be needed," World Health Organization (WHO) spokeswoman Fadela Chaib told Reuters in Geneva.
"For the time being there is no outbreak of diseases reported except for cases of diarrhea and respiratory infections."
'The Floods Took Everything'
"It was raining last night and we sat in the open as we are at the moment," Saeed Jan, a young man whose house was destroyed by floods, told Reuters.
"We're receiving some relief goods but nothing else. We are in desperate need of tents and shelter."
Sher Wali, a middle-aged man whose house was destroyed by floods, said: "When rationed supplies come, the village elders give them out to their own people and the poor get nothing.
"The floods took away everything. Ration officials demand identity cards. Where can we produce identity card from? We lost those cards with our belongings. So we are facing difficulties."
UN chief Ban Ki-moon pledged aid of up to $10 million while the Untied States has pledged an initial $10 million and Britain has pledged $8 million.
