Fourteen soldiers have been killed after “heavily-armed terrorists” ambushed a convoy in the western Niger region of Tillaberi.

“After a fierce battle… seven police and seven national guards were killed” Wednesday, the interior ministry said in a statement on Thursday.

“A guard has been listed as missing,” the ministry said, adding, “the enemy suffered many losses.” It did not give details.

The security forces had been escorting a team to carry out voter registration in the district of Sanam ahead of presidential and legislative elections due in late 2020, it added.

The team was “secured and returned to Sanam safe and sound,” the statement said.

Niger, a poor, landlocked country in the heart of the Sahel, is on the front line of a jihadist insurgency.

Its troops are fighting Boko Haram militants on the southeast border with Nigeria and jihadists allied with the Islamic State group in the west near Mali.

On December 10, 71 soldiers were killed in Tillaberi when hundreds of jihadists attacked a military camp with shelling and mortars.

It was the worst single toll since jihadist violence spread from Mali in 2015.

Niger is part of a five-nation anti-jihadist task force known as the G5, set up in 2014 with Burkina Faso, Mali, Mauritania and Chad.

Burkina Faso on Thursday was observing its second day of mourning after a wave of jihadist attacks in the north of the country left 42 dead, also its worst one-day casualties since 2015. (Channels TV)
