A senior Sudanese security official says 14 people were killed during last week's protests in Western Darfur but denied that police were responsible.

In remarks published by the pro-government Al-Sudani daily on Saturday, Police Chief Atif Fadul said 13 civilians and six policemen were wounded in the protests, which took place in front and inside the governor's office on Jan. 10. Those figures are the first official toll to emerge from the unrest.

The African Union has expressed concern over "continued tension" in and around the town of Genaina in Western Darfur after residents of Mouli, near the border with Chad, staged a demonstration against an assault by a pro-government militia on their village.

Fadul said police showed restraint. Sudanese security forces have violently dispersed protests in the past.
