Honduran migrant, clutching two small children, flees tear gas

In the shot, taken on Sunday, you can see Honduran mother Maria Meza, 35, grabbing the thin arms of her two 5-year-old twin daughters Cheili and Saira as they frantically run from a tear gas canister spewing fumes.Just before the tear gas was fired, I had followed some of the migrants as they approached a section of the border fence recently reinforced with razor-studded coils.
