Associated Press photographer Burhan Ozbilici won the 2017 World Press Photo competition Monday, with jurors and colleagues lauding his courage and composure in capturing his image of a gun-wielding off-duty Turkish policeman standing over the body of Russia's ambassador, whom he had just fatally shot.
Ozbilici's image was part of a series titled "An Assassination in Turkey" that also won the Spot News - Stories category. The photos were captured in the moments before and after policeman Mevlut Mert Altintas drew a handgun and shot Ambassador Andrei Karlov at a photo exhibition in Ankara on December 19, 2016.
Ozbilici said his professional instincts kicked in despite the shocking scene unfolding in front of him. (Source: AP)

His mouth is wide open as he shouts angrily. The ambassador's body lies on the floor just behind Altintas. (AP Photo/Burhan Ozbilici, File)
