Two Japanese citizens and a family member of another nationality were among those evacuated from Niger with the support of France following a military coup in the western African state, Japan's top government spokesman said Wednesday.

Around 10 Japanese nationals in total were in the country as of Tuesday and all have been contacted, Chief Cabinet Secretary Hirokazu Matsuno said during a news conference.

Japan will continue to make utmost efforts to secure the safety of its nationals in collaboration with France and other countries, Matsuno said, days after the military coup sparked protests in Niger against France, its former colonial ruler.
