African immigrants are seen on the street pavements in the southern port city of Aden, Yemen, March 18, 2020. Yemen's government declared a number of precautionary measures in an attempt to curb the outbreak of the coronavirus in the war-ravaged Arab country. Despite these measures, Yemenis said that thousands of African immigrants and asylum-seekers continue flocking into the country via the illegal border crossings, as the authority over Yemen's land, air, and sea crossings is fractured between the Saudi-backed government and the Iranian-backed Houthis without any coordination, making it difficult for the rival governments to contain coronavirus.
