Suspected Islamic extremists attacked a military installation in western Niger near the border of Mali on Tuesday, killing at least 70 soldiers in one of the country's deadliest onslaughts in recent history.
President Mahamadou Issoufou tweeted on Wednesday that he would be cutting short his overseas trip to Egypt so he could return home to deal with the crisis, The Associated Press reported. A presidential adviser who spoke with the AP on condition of anonymity confirmed the body count of the overnight attack.
The area has been seen as a hotbed of terrorist activity, Islamic extremism and kidnapping.
Two years ago, four U.S. service members were killed, along with four Nigerien soldiers, when they were ambushed by militants just 30 miles from the sight of the recent carnage.
Nigerien and French forces have been unable to quell the violence as reports of military outpost attacks have increased, due to their cache of weapons and vehicles.
The extremists are reportedly taking advantage of the area's instability in an attempt to initiate a jihadist takeover.
After intervening in 2013 to oust various jihadists from power, France has now launched its biggest overseas military operation in West and Central Africa to assist with the threat.
Macron is expected to clarify France's future role in the region during this week's summit with West African leaders.
