'Hero rats' used to sniff out landmines

'Hero rats' detect landmines

Giant rats are being trained to sniff out buried landmines in war zones.

Landmines are placed in the ground during a war to seriously injure or kill the enemy.

But they often remain undiscovered for many years and ordinary people can end up stepping on them by accident.

The rats are being used because they are light enough to walk over the devices without blowing them up and can search wider areas more quickly than humans.

Ayshah has been looking into the life-saving work of these roving rodents.
