Pakistan floods: disaster is the worst in the UN's history

The United Nations has rated the floods in Pakistan as the greatest humanitarian crisis in recent history with more people affected than the South-East Asian tsunami and the recent earthquakes in Kashmir and Haiti combined. Although the current 1,600 death toll in Pakistan represents a tiny fraction of the estimated 610,000 people killed in the three previous events, some two million more people - 13.8 million – have suffered losses requiring long or short-term help.
