Sudan's hidden danger of mines

As residents return to Sudan's capital, Khartoum, they are facing a deadly new threat from unexploded ordnance and landmines left behind by years of fighting.

Aid groups warn that hundreds of people have already been injured or killed by the hidden weapons as they attempt to rebuild.

Deminers are working to clear contaminated areas, but the scale of the problem is immense.

The ongoing conflict has created a major humanitarian crisis and a lasting legacy of danger.
