The United Nations General Assembly is holding an emergency session today to raise emergency aid for the millions of Pakistanis devastated by massive floods. The UN says vital supplies have reached just one million of the eight million people in urgent need. The number of Pakistanis left permanently homeless by the floods has been doubled to four million, with some 20 million people displaced overall. The US is expected to announce it’s increasing aid to $150 million from the $90 million pledged so far.
