The UN's Office for the Coordination of Humanitarian Affairs (OCHA) estimates that some 4.5 million Syrians have been displaced within Syria's borders as the country's internecine conflict grinds on, exacting its brutal toll. In Idlib province alone, 300,000 IDPs struggle to survive. (..) Fuel and food prices prices are soaring with wheat production down, silos destroyed and farmers fleeing. Fears continue to mount that Syria's internally displaced will go hungry with aid agencies unable to reach many in need because of security risks. "The Syrian crisis has resulted in heightened vulnerability, massive movements of the population inside the country and a substantial setback in living conditions," the UN Food and Agriculture and World Food Programme said in a joint report earlier this month.
