Angola's civil war left 1,100 active minefields. The attitude had been that clearing mines is man's work until a nonprofit stepped in. Now nearly 400 women deminers tread carefully — and courageously.

Angola's civil war left 1,100 active minefields. The attitude had been that clearing mines is man's work until a nonprofit stepped in. Now nearly 400 women deminers tread carefully — and courageously.

The attack targeted workers clearing landmines with the HALO Trust charity. The militant Islamic State group claimed responsibility. Afghanistan is one of the world's most heavily mined countries.

In the last four years, the rat named Magawa has helped to clear over 1.5 million square feet of land. The animal has detected dozens of land mines in Cambodia and is believed to have saved lives.
