Flash floods sparked by torrential rain in largely desert Saudi Arabia have killed seven people over the past three days, the civil defence authority said on Wednesday.
Five other people are still missing after parts of the capital Riyadh and the northeastern city of Arar were inundated, authority spokesman Colonel Abdullah al-Harithi told the official SPA news agency.
The storms that have accompanied the downpours have brought down power lines, sparking outages in parts of north Riyadh.

Saudi Arabia normally experiences such low rainfall that religious leaders often organise special prayers for rain.
