UNITED NATIONS (AP) — An initial United Nations assessment of the impact of Afghanistan’s recent deadly earthquake found 5,230 homes destroyed and 672 damaged in 49 villages — but the U.N. hasn’t been able to reach most remote villages.

Shannon O’Hara, the coordination chief for the U.N. humanitarian office in Afghanistan, reported that damaged roads have made it challenging to assess the situation in 441 affected villages.

The quake, which struck on August 31, killed at least 2,200 people, affecting up to 500,000, including many children returned from neighboring countries. As the U.N. team navigated harsh terrain, families were seen displaced, some still wearing clothes from the night of the earthquake.

O’Hara emphasized the overwhelming needs for clean water, food, tents, and sanitation, warning of potential cholera outbreaks due to the dire conditions. As winter approaches, the urgency of humanitarian aid is vital to the survival of these communities.
