Niger declared three days of national mourning on the event date of 2025-03-22 after a deadly attack on a mosque in the country’s southwest left at least 44 people dead and 13 wounded, according to Al Jazeera’s report based on government statements.

The attack took place in the Fambita quarter of Kokorou, a rural border town in the Tillaberi region near the frontier with Burkina Faso. Niger’s interior ministry said the assault happened in the early afternoon while worshippers were attending Friday prayer during Ramadan. The ministry described the attackers as heavily armed and said they surrounded the mosque before carrying out what it called a massacre with unusual cruelty.

The defence ministry blamed the Islamic State in the Great Sahara, also known as EIGS, which is affiliated with the Islamic State group. Al Jazeera reported that there was no immediate reaction from the armed group to the accusation. The report also said the attackers set fire to a local market and nearby homes, widening the damage beyond the mosque itself.

The toll placed the incident among the deadliest recent attacks on civilians in Niger’s insurgency-hit southwest. The country has faced persistent violence linked to extremist groups active across the wider Sahel, where fighters associated with al-Qaeda and Islamic State have moved across borders and repeatedly attacked villages, security outposts and transport routes. Al Jazeera noted that since July 2023, at least 2,400 people have been killed in Niger according to ACLED, which tracks conflict events.

The government said it would hunt down the perpetrators and put them on trial. In the immediate aftermath, authorities were also dealing with the wounded and with the wider shock of an attack that hit during a moment of worship. The report did not provide a full final casualty count beyond the ministry’s statement that at least 44 had been killed.

The attack comes against a broader backdrop of instability in the Sahel, where multiple governments have struggled to contain armed groups and have increasingly turned away from Western security partnerships since coups in Mali, Burkina Faso and Niger. That regional context has made border areas especially vulnerable to raids and reprisals.

For Niger, the mourning period marks both an official response and a recognition of the scale of the loss. But the immediate practical challenge remains the same: protecting civilians in a region where attacks can erupt with little warning, and where even places of prayer are not immune from violence.
