Kneeling down in the middle of a minefield, Noralba Guarin uses a spade to scrape away the hard red earth on a remote wooded hillside in southwestern Colombia.
Sweating under her protective anti-explosive vest and shatterproof mask, she searches for landmines, a deadly legacy of 52 years of civil war in Colombia, one of the most mine-scarred countries in the world.
War forced Guarin to flee her home twice, once aged 13 to avoid being forcibly recruited by rebels from the Revolutionary Armed Forces of Colombia (FARC), and years later when rebels threatened her again when she was heavily pregnant.
Now Guarin works for the British-based Halo Trust, a demining group, clearing the mines the FARC planted in their fight against government troops.
