JALALABAD, Afghanistan, July 16 (Xinhua) -- One woman and four children were killed after the rooftop of a house collapsed in Afghanistan's eastern Nangarhar province overnight, provincial government spokesman said Tuesday.

"One woman was also wounded in the incident which occurred at midnight in Barpchir village of Pachir Wa Agam district, south of provincial capital Jalalabad city," spokesman Attaullah Khogyani told Xinhua.

The injured woman was shifted to the district hospital, he said.

Residents in Afghan villages and cities live in traditional muddy and old houses that easily collapse in a natural disaster, raining or snowing.

Aging of the house was blamed for the incident, the official said.
