In the past week, 331,140 people were recorded to have been living in displacement from the East and the West parts of the city of Mosul since 17 October 2016. During the period between 25 February and 16 April, a total of 323,000 individuals were displaced from West Mosul. According to OCHA, as many as 500,000 people remain in ISIL-controlled districts in western Mosul, including 400,000 people that are in the densely populated old city of Mosul. Humanitarian partners are working around-the clock to expand emergency sites and camps to shelter the hundreds of thousands more who may flee in coming days and weeks.
