At least 10 gold miners have been killed in an accident in northern Sudan, and more than 20 others injured.
Local media have blamed the collapse of the gold mine on the use of heavy machinery.
Accidents are not uncommon in Sudan’s under-regulated mining industry.
Six months ago 11 people died in a similar incident in the same part of north Sudan, while other fatalities have been reported in the western Darfur region and Kordofan in the south.
Over two million people are believed to be working in artisanal mining in Sudan.
