(CNN) Amal Hussein, a 7-year-old Yemeni girl whose photograph in The New York Times became a symbol of the country's long-running conflict, has died, Yemen's Houthi-held Health Ministry said.

The image by Pulitzer Prize-winning photojournalist Tyler Hicks showed the emaciated girl lying on a bed October 18 at a mobile UNICEF clinic in Aslam, Yemen.

The stark photograph of such a young child in pain -- Hussain was suffering from severe acute malnutrition -- was emblematic of the brutal civil war that has pushed millions to the brink of starvation.

Hussein's mother, Mariam Ali, said her heart was "broken," the Times reported Thursday.
