Mustapha, 60, a brick maker, piles up bricks after removing them from a kiln at an open-air factory on Tuti Island, Khartoum, Sudan, February 20, 2020.

We usually get the mud when the Nile overflows", said Mustapha. REUTERS/Zohra Bensemra SEARCH "BENSEMRA NILE" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES.
