Paul Hansen’s dramatic image of a funeral procession in Gaza has been named 2012’s World Press Photo of the Year. The photo shows a group of men carrying the corpses of two children who were killed in Gaza City in November when their house was destroyed in an Israeli missile strike. Their father’s body is carried behind on a stretcher.

Mr. Hansen, who has covered Gaza about a half dozen times over his career, took the photo for the Swedish daily newspaper Dagens Nyheter. In a phone conversation Friday morning he described the image as capturing “an emotionally charged moment.”

“It was a horrible day,” said Mr. Hansen, who was recently named the 2012 Newspaper Photographer of the Year in the Pictures of the Year International competition. “It was so sad and heart-wrenching and hit me on personal level, because I have a child myself.”

Santiago Lyon, vice president and director of photography for The Associated Press, was chairman of the jury, and said the winning photo worked powerfully on many levels.

“I’ve always maintained that a successful photograph should reach you on at least one of three planes,” he said during a telephone interview Friday morning. “Those planes would be your head, your heart and your stomach, and I think this picture works on all three. So when we were looking at it in those final stages, we found it to be very powerful on all three levels, and very layered and very complex, but at the same time very simple and very direct.”

The image draws some of that power from its striking — almost stylized — lighting and tones. Mr. Hansen, 48, said the unusual look resulted when light bounced off the walls of the alley for just a few moments.

Mr. Lyon said the jury carefully examines the winning images for post processing. He said they decided Mr. Hansen’s photo was “within the acceptable industry parameters.” He added: “Everybody has different standards about these sorts of things, but as a group we felt that it was O.K.”

World Press Photo is a 56-year-old nonprofit foundation with headquarters in Amsterdam, where the announcement of this year’s winners was made on Friday morning.

Mr. Lyon said that he personally looked at over 75,000 images that included “a lot of powerful material” from Syria and Gaza as well as “a fair amount of material around women’s issues and gay and lesbian issues.”
