The French government warns people against travelling to large parts of Niger where militant groups including Boko Haram and affiliates of Islamic State operate.
The Koure Giraffe Reserve southeast of the capital Niamey is a popular attraction in Niger, a huge country that borders seven countries in an unstable region including Libya, Mali, Chad and Nigeria.
Militants linked to Islamic State killed four U.S. soldiers in an ambush in Niger in Oct. 2017, an attack that increased scrutiny of the U.S. counter-terrorism operations there.
France, a former colonial power in the region, also launched a coalition of West African and European allies in June to fight Islamist militants in the Sahel region that includes Niger.
It has deployed thousands of troops in the arid region south of the Sahara desert since 2013. But violence by groups linked to al Qaeda and Islamic State has been on the rise.
