The United Nations humanitarian agency is warning that about 5.7 million Pakistani flood survivors will face a serious food crisis in the next three months, as the death toll from the deluge rose on Monday. Pakistan’s National Disaster Management Authority reported that floods fuelled by abnormally heavy monsoon rains have killed 1,695 people, affected 33 million, damaged more than 2 million homes and displaced hundreds of thousands now living in tents or makeshift homes. The UN Office for the Coordination of Humanitarian Affairs in its latest report on Saturday said the current floods are expected to exacerbate food insecurity in Pakistan and said 5.7 million people in flood-affected areas will be facing a food crisis between September and November. Even before the floods, according to the World Health Organisation, 16 per cent of the population was living in moderate or severe food insecurity. The UN said in a tweet on Monday that the agency and other partners have scaled up their flood response.
