Pakistan warned that floods triggered by monsoon rains could affect millions more people this year, but claimed it was better prepared after a massive humanitarian crisis in 2010. Monsoon-triggered floods in 2010 affected up to 21mn people and killed an estimated 1,750 people, causing an estimated $10bn in losses and hammering the already depressed economy.
