Authorities in Niger declared three days of national mourning June 26 after an ambush on security forces near the village of Tassia resulted in the deaths of at least 20 soldiers and one civilian. Tassia lies in the western Tillabéri region bordering Mali and Burkina Faso, long a stronghold of jihadist​ insurgents. The incident highlights the growing challenges facing the ruling junta, one year after it came to power in a July 2023 coup, overthrowing the civilian government led by Mohamed Bazoum.
