(..) World Food Programme (WFP) spokesman Amjad Jamal said the organisations' workers were urgently trying to reach flood areas in the northwest cut off from food supplies, which a U.N. aid agency said devastated the lives of over 3 million people. "You can imagine for five or six days floods have caused havoc in these areas. People have lost their food stocks. The markets are not up and running. Shops have collapsed. People are definitely in the greatest need of food," Jamal said.
