TOPSHOT - Abu Zakkour, Aleppo's so-called 'yellow man' walks along with pedestrians in the central Saadallah al-Jabiri square in the northern Syrian city on February 11, 2019. - Dressed in yellow from head-to-toe, Abu Zakkour is hailed as part of the "heritage" of the northern Syrian city of Aleppo, along with its medieval citadel and its ancient covered markets. For nearly 36 years, the 70-year-old has strictly abided by a full monochrome look, sporting only yellow apparel and accessories. (Photo by LOUAI BESHARA / AFP)
