A speeding lorry trying to overtake a car crashed into a passenger bus on a road in northern Sudan, killing 13 people and injuring 15.
Sudanese police said the accident happened near the village of Dongola on the Nile River, around 500 miles north of the capital, Khartoum.
Streets were slick as heavy rains and gale force winds pummelled much of the country, causing severe flooding in some towns.
Images circulating online showed the two big vehicles crumpled and overturned by the roadside.
Both drivers and four police officers travelling on the bus were among those killed, officials said.
The 15 injured were taken to a hospital, where some were reported in critical condition.
