In this July 12, 2019 photo, 35-year-old Mohammed Eissa walks along a highway, around 50 kilometers (31 miles) from Djibouti. Eissa picked up rides from his home to the border with Djibouti, then walked. His second day there, he was robbed at knifepoint by several men who took his money. The next day, he walked six hours in the wrong direction, back toward Ethiopia, before he found the right path again. (AP Photo/Nariman El-Mofty)
