France will pull its soldiers out of Niger following a July coup in the West African country, President Emmanuel Macron said on Sunday, dealing a huge blow to French influence and counter-insurgency operations in the Sahel region, according to Reuters.

Macron said 1,500 troops would withdraw by the end of the year and that France, the former colonial power in Niger, refused to “be held hostage by the putschists.”

France’s exit, which comes after weeks of pressure from the junta and popular demonstrations, is likely to exacerbate Western concerns over Russia’s expanding influence in Africa. The Russian mercenary force Wagner was already present in Niger’s neighbour Mali.

French influence over its former colonies has waned in West Africa in recent years, just as popular vitriol has grown. Its forces have been kicked out of neighbouring Mali and Burkina Faso since coups in those countries, reducing its role in a region-wide fight against deadly Islamist insurgencies.

Until the coup, Niger had remained a key security partner of France and the United States, which have used it as a base to fight an Islamist insurgency in West and Central Africa’s wider Sahel region.

France’s military base in Niger’s capital, Niamey, had become the epicentre of anti-French protests since the July 26 coup.

Groups have regularly gathered on the street outside to call for the exit of troops stationed in the capital. On one Saturday this month, tens of thousands rallied against France, slitting the throat of a goat dressed in French colours and carrying coffins draped in French flags.

Pro-coup demonstrators in Niamey have waved Russian flags, adding to Western countries’ fears that Niger could follow Mali’s lead and replace their troops with Wagner fighters.

Before his death in a plane crash last month, Russian mercenary chief Yevgeny Prigozhin spoke in a social media clip of making Russia greater on all continents and Africa more free. Wagner’s future has been unclear since his demise.

Wagner is also active in Central African Republic and Libya. Western nations say it is also present in Sudan, though it denies this. Russian President Vladimir Putin has called for a return to constitutional order in Niger.

French nuclear power plants source a small amount – less than 10% – of their uranium from Niger, with France’s state-owned Orano operating a mine in Niger’s north.

Macron said he still regarded democratically elected President Mohammed Bazoum, currently held prisoner by the coup leaders, as Niger’s legitimate leader and had informed him of his decision.
