Remembering photojournalist Anja Niedringhaus

Veteran AP journalists Anja Niedringhaus and Kathy Gannon were traveling with election workers, soldiers and police in Khost province in Afghanistan when a police commander approached and shot them. Niedringhaus, a Pulitzer Prize-winning photographer, was killed and Gannon was hospitalized. Kathleen Carroll, executive editor of The Associated Press, remembers Niedringhaus with Hari Sreenivasan.
