This is the story of the murder of two aid workers in Mexico. The men fed Central American migrants traveling north through Mexico on a freight train that stopped near their home.
They were critical of both corrupt police, who abused and extorted the migrants, as well as the organized crime gangs that kidnapped and robbed them.
It wasn't hard to find the two men — they were never far from the train tracks — but there were no witnesses to their deaths, and police won't comment about the case. The double homicide didn't even get a mention in the local press.
The shrine of Imam Ali in the Iraqi city of Najaf is a vast gold-domed edifice, where Shiite Muslims from all over the world gather to pray.
But just a few minutes drive away, are travelers of a different, shabbier kind. A long row of cinder block and sheet metal buildings is draped in bright flags with religious slogans. Usually, these are for pilgrims to sleep in. But right now, they're spilling over with displaced Iraqi families.
"It's tough for the children," says Zaira Raqib, a mother of four of them. "We know we're displaced, but they don't understand."

Independent polls show people overwhelmingly oppose the continued occupation of city streets because it's inconvenient and appears to be futile.
As Nigeria's military continues to battle Boko Haram fighters for control of towns and territory in the turbulent northeast, fearful residents are leaving — or being driven out of town. More than 200 schoolgirls, abducted by the Islamist extremists in April, are still missing.
