Thousands affected by a deadly earthquake in eastern Afghanistan are in need of clean water and food and are at risk of disease, an Afghan health ministry official said on Sunday, days after a UN agency warned of a cholera outbreak in the region.

Iran PressAsia: At least 1,000 people were killed, 2,000 injured and 10,000 homes destroyed in Wednesday's earthquake, after which the UN humanitarian office (OCHA) warned that cholera outbreaks in the aftermath are of particular and serious concern.

"The people are extremely needy for food and clean water," Afghanistan's health ministry spokesperson Sharafat Zaman told Reuters, adding officials had managed medicines for now but handling those who had lost their homes would be a challenge.

"We ask the international community, humanitarian organizations to help us for food and medicine, the survivor might catch diseases because they don’t have proper houses and shelters for living," he said.

The disaster is a major test for Afghanistan's hardline Taliban rulers, who have been shunned by many foreign governments due to concerns about human rights since they seized control of the country last year.

Helping thousands of Afghans is also a challenge for countries that had imposed sanctions on Afghan government bodies and banks, cutting off direct assistance, leading to a humanitarian crisis even before the earthquake.

In Kabul, hospitals more used to treating victims of war have opened their wards to earthquake victims, but a majority of people remain in the areas destroyed by the earthquake.
