More than 400 West Africans have been rescued in the desert in northern Niger, the International Organization for Migration (IOM) has said, Reuters news agency reports.
Search and rescue teams found the migrants, split in two groups, at the desert border town of Assamaka on Monday and Tuesday, the IOM added.
The one group was made of 347 people who had arrived in Assamaka on foot on Monday. The group was made up of nationals from 13 countries, including Mali, Guinea and Senegal. A further 92 were found on Tuesday, Reuters quoted the IOM as saying.
Niger is a transit point for thousands of migrants on their way to Libya or Algeria, from where they try to cross the Mediterranean to reach Europe.
