Pakistan's Prime Minister Yusuf Raza Gilani says, 20 million people have been affected by the country's floods, a much higher estimate than the UN's 14 million. He was addressing the nation during much muted celebrations of Pakistan's independence from British rule 63 years ago. In his address, Mr Gilani said 20 million were now homeless, although it was unclear how many of those people were briefly forced to leave their homes and how many had lost their houses altogether. UN Secretary General Ban Ki-moon is expected to visit the country during the weekend.
