World Press Photo Award for a photo that made history and changed policy

The picture of the wailing toddler caused a public outcry about Washington's controversial policy to separate thousands of migrants and their children.

The haunting image of a little girl crying helplessly as she and her mother are taken into custody by US border officials on Thursday won the prestigious World Press Photo Award.

Judges said veteran Getty photographer John Moore's picture taken after Honduran mother Sandra Sanchez and her daughter Yanela illegally crossed the US-Mexico border last year showed “a different kind of violence that is psychological”.

The picture of the wailing toddler was published worldwide and caused a public outcry about Washington's controversial policy to separate thousands of migrants and their children.

US Customs and Border Protection officials later said Yanela and her mom were not among those separated, but the public furor “resulted in President Donald Trump reversing the policy in June last year,” the judges said.

Moore was taking pictures of US Border Patrol agents on a moonless night in the Rio Grande Valley on June 12 last year when they came across a group of people who tried to cross the border.

“I could see the fear on their faces, in their eyes,” Moore told the US-based National Public Radio broadcaster in an interview shortly afterwards.

As officials took their names, Moore said he spotted Sandra Sanchez and her toddler who started wailing when her mom put her down to be searched.

“I took a knee and had very few frames of that moment before it was over,” said Moore, who had been covering the US-Mexico border for a decade.

At the awards ceremony in Amsterdam, Moore told AFP: “I wanted to tell a different story.”

“For me it was a chance to show a view of humanity that is often only related in statistics,” the 51-year-old photographer said.

“I think an issue like this, immigration issues, resonates not just in the United States, but around the world,” Moore also told several hundred guests at the awards.

The sensitive issue of immigration was further highlighted at Thursday's awards.

Judges chose Dutch-Swedish photographer Pieter Ten Hoopen's images of the 2018 mass-migrant caravan to the US border as its winner in the “World Press Photo Story of the Year Award”.

Ten Hoopen's pictures, which show families and children as they made their way from Honduras in mid-October to the US border “showed a high sense of dignity,” one of the judges said.

Ten Hoopen thanked the migrant families, saying without them his award would not have been possible.

Trump said on Tuesday he won't resume separating children of undocumented migrants, but insisted that the policy did prevent people from illegal border crossings like a trip to “Disneyland”.

His words came after he announced the departure Sunday of the official in charge of fighting illegal immigration - Homeland Security Secretary Kirstjen Nielsen.

Judges selected this year's winners from 78,801 images entered by 4,738 photographers worldwide, the Amsterdam-based organizers said.
