Mexican farmers revolt over sending water to US during drought

Country has one month to deliver outstanding 289m cubic metres and ensure water for 14 major cities and growers

Mexican farmers in the drought-stricken state of Chihuahua are pitted against riot squads from the national guard in an increasingly violent standoff over their government's decision to ship scarce water supplies to the United States.

The confrontation has already led to bloodshed: earlier this month, a woman was shot dead and her husband was wounded after guardsmen opened fire on farmers wielding sticks and stones.
