Suicide bombers have killed at least 20 people in a French-run uranium mine in northern Niger.
About 50 people were injured at the mine when a suicide bomber drove into the front of the plant and blew up his vehicle, ABC reports.
The mine, located in the remote town of Arlit, has also reported key infrastructure has been badly damaged.
Islamist militants MUJWA are claiming responsibility for the attack.
The group which is also known as Movement for Unity and Jihad in West Africa is an offshoot of terrorist group Al Qaeda.
MUJWA says the attack was at act of revenge for Niger's involvement in the French-led intervention in Mali.
Niger's president, Mahamadou Issoufou, has also confirmed French Special Forces have now moved in to protect the plant.
