As Yemen's war grinds into its fifth year with peace efforts stalling, ten-year-old Afaf's father sees little hope he will be able to give his starving daughter the food or healthcare she needs. Across Yemen's remote mountain villages, the country's war-induced economic crisis has left parents destitute, hungry and watching their children waste away from malnutrition and unclean water. "Before the war we managed to get food because prices were acceptable and there was work," 40-year-old Abdu said from al-Jaraib, a small agricultural village in the hills of Hajjah province in northwest Yemen. "Now they have increased significantly and we rely on yoghurt and bread for nutrition." Four years of conflict have pushed Yemen, which was already one of the poorest Arab states, to the brink of famine. War has cut transport routes for aid, fuel and food, reduced imports and caused severe inflation. Households have lost their incomes because public sector wages are not being paid and conflict has forced people from their homes and jobs. The United Nations says about 80 percent of the population needs some form of humanitarian assistance and two-thirds of all districts in the country are in a "pre-famine" state.

Work is scarce and they live off payments for odd jobs and a monthly government handout of heavily-subsidised basic food supplies. They have taken to inventing meals with what little they have like lentils with plantain from the trees in their backyard. Guitia said her son had lost weight over the past five months until Caritas gave them some nutritional supplements. REUTERS/Carlos Garcia Rawlins SEARCH "RAWLINS GUZMAN" FOR THIS STORY.
