The leader of Islamic State’s affiliate in West Africa has claimed responsibility for an attack that killed four United States special forces and four soldiers from Niger Republic in October, Mauritania’s independent Nouakchott News Agency (ANI) reported on Saturday.

The troops were killed when their joint patrol was attacked near the village of Tongo Tongo, on the Mali-Niger border, on October 4 by dozens of militants armed with machine guns and rocket-propelled grenades.

The incident drew attention to the little-known US military presence in Niger Republic – it has 800 troops stationed there – and became a major publicity headache for President Donald Trump’s administration.

Security officials had identified the perpetrators as Islamist militants loyal to Abu Adnan al-Sahrawi, the leader of Islamic State in the Greater Sahara operating along Mali’s border with Niger and Burkina Faso, but there had previously been no confirmation from al-Sahrawi himself.

“We claim the attack which targeted the American commandos in the village of Tongo Tongo,” Sahrawi, who makes public statements only very rarely, was quoted by ANI as saying.

Privately-owned ANI sometimes enjoys privileged access to information on movements of Sahara-based Islamist fighters. Last year it broke news that Mali’s main jihadist groups had merged, and in 2013 it had exclusive reports about a militant attack on a gas plant in Algeria in which 38 hostages were killed.

In the statement Sahrawi also claimed a car bomb attack on French troops on Thursday near Mali’s city of Menaka, ANI reported. He said it had “killed many of them”, although the French military said in a statement that the attack had merely wounded three troops.

Lawlessness across the Sahara has enabled jihadist groups to thrive and launch increasingly deadly attacks on local and Western targets there and in the semi-arid Sahel south of it. They are seen as the biggest threat to the region’s stability. (Reuters)
