Kim Kyung-Hoon has taken countless photos in his 13 days covering a migrant caravan in Mexico. But one image in particular stands out: The photo of a Honduran mother, Maria Lila Meza Castro, and her 5-year-old twin girls running away from tear gas.
"This has all the elements in one picture," the Reuters photojournalist told CNN. "We can see the border, the tear gas, the children using diapers, barefoot."
The family was among more than 100 migrants near the Mexico-US border in November when a few men tried to dismantle a wire fence separating the two countries, Kim said.
That's when border officials unleashed tear gas, which affected bystanders including the Honduran family that Kim photographed.
The image also captured imaginations because the mother was wearing a shirt from Disney's "Frozen" -- a movie in which a sister sets off on a brave journey for a better life.
Immediately after the tear gas was released, the woman and girls fled to a migrant camp in Tijuana, about a 30-minute walk away.
Meza Castro and her children were permitted into the US on December 17, Sandra Cordero, with the group Families Belong Together, told CNN.
