Reuters photographer Mohammed Salem captured this year's prestigious World Press Photo of the Year award Thursday with a depiction of loss and sorrow in Gaza, a heartrending photo of a Palestinian woman cradling the body of her young niece. The photograph, taken in Khan Younis just days after Salem's own child was born, shows 36-year-old Inas Abu Maamar holding five-year-old Saly, who was killed along with her mother and sister when an Israeli missile struck their home.
