Militants affiliated to Islamic State group have taken Tidermene in Mali, further isolating the regional capital, Menaka, in a region that has fallen almost entirely under their control, officials and witnesses told AFP on Wednesday.

Tidermene's fall follows months of fighting by Islamic State in the Greater Sahara, or ISGS, to seize the northeastern village of a few thousand inhabitants about 75 kilometers north of Menaka.

All the region's main administrative subdivisions are now under the group's control.

The village was captured Monday night.

“Tidermene has fallen into the hands of Daesh,” an elected official from the town, who has retreated to Menaka, told AFP, using the Arabic acronym for the Islamic State organization.

“They are distributing Qurans to the population [and] moving around town with weapons,” he said.

He and others spoke on condition of anonymity for fear of reprisals.

Another elected official told AFP the militants had instructed the village's residents to continue with business as usual, but to be prepared to begin paying “zakat,” an Islamic tax.

A major ISGS offensive has been underway since early 2022 in the region of Menaka and that of Gao, further west.

The regions have seen intense battles between ISGS fighters and the al Qaida-linked Group to Support Islam and Muslims (JNIM), as well as with former Tuareg independence fighters who signed a peace deal in 2015, and loyalists who once fought the independence fighters.

The militants have stepped into a vacuum left when French forces departed last year, experts say.

Hundreds of civilians have been killed in the violence, and communities have been displaced en masse.

Some have fled across the border to Niger.

The U.N. and human rights organizations say militants have carried out punitive attacks against communities they accuse of helping the state or refusing to join their ranks.

One Tidermene refugee now in Menaka told AFP that, given the town is a former JNIM stronghold, ISGS fighters are now seeking out civilians who own weapons or walkie-talkies.

“The Malian army controls Menaka and is ensuring the protection of civilians,” an army officer told AFP when asked about the capture of Tidermene.

The Malian military, the U.N. stabilization mission and armed groups loyal to the state remain present in Menaka.
