Swedish photographer Paul Hansen won the 2012 World Press Photo award Friday for newspaper Dagens Nyheter with a picture of two Palestinian children killed in an Israeli missile strike being carried to their funeral.

The picture shows a group of men marching the dead bodies through a narrow street in Gaza City. The victims, a brother and sister, are wrapped in white cloth with only their faces showing.

"The strength of the pictures lies in the way it contrasts the anger and sorrow of the adults with the innocence of the children," said jury member Mayu Mohanna of Peru. "It's a picture I will not forget."

World Press Photo, one of photojournalism's most prestigious contests, issued awards in nine categories to 54 photographers of 32 nationalities.

Hansen's Nov. 20 shot won top prize in both the spot news single photograph category and the overall competition. It portrays 2-year-old Suhaib Hijazi and her 3-year-old brother Muhammad, who were killed when their house was destroyed by the Israeli attack. They are being carried by grieving uncles, as their father Fouad was also killed, and his body can be seen in the background of the picture. The children's mother, whose name was not provided, was in intensive care.

"This prize is the highest honor you can get in the profession," Hansen told The Associated Press. "I'm very happy, but also very sad. The family lost two children and the mother is unconscious in a hospital."

"These situations are so visually complex," he added. "It's difficult to convey the emotions, to translate what is happening. The light is harsh and there are a lot of people.

"But in the alley the light bounced off the walls, so I thought this is a place where you can see that it's a procession. ... You get the depth in the image, and the bouncing light."

The photo was captured during the eight-day military operation, dubbed Operation Pillar of Defense, mounted by Israel against Hamas militants in the Gaza Strip.

Violence in the Middle East, and its effect upon civilians, was the dominant theme in the hard news categories.

The Associated Press won seven awards in all, including top prizes for a spot news series for Bernat Armangue of Spain for photos he took in Gaza during November; and for Rodrigo Abd of Argentina for general news single photograph, with a picture of a woman with a bloodstained face weeping in Idib, Syria, on March 10.

She was identified as Aida, and her photo of silent grief is in some ways a reverse image of Hansen's winning shot. She received severe injuries when her house was shelled by the Syrian Army, killing her husband and two children.

In other categories, Wei Seng Chen of Malaysia won in the sports singles category with a shot of what might be considered a local "extreme sport": A man clutching the tails of two bulls as they pull him through a watery rice field in Batu Sangkar, Indonesia.

The competition also includes portrait series, scenes from everyday life, and nature photography, among others.

The contest drew entries from professional press photographers, photojournalists and documentary photographers across the world. In all, 103,481 images were submitted by 5,666 photographers from 124 countries.

Hansen will receive a €10,000 prize at ceremonies and the opening of the year's exhibition April 25-27th in Amsterdam.
