This is “in stark violation of international human rights law and humanitarian law,” he emphasised, adding that an impartial investigation should be instituted to bring those responsible to justice.

Regional insecurity

The attack came in the context of a general deterioration in the security situation in the wider Sahel region.

In recent years, the Sahel has seen a major uptick in violence, following the expansion of armed groups linked to al-Qaeda and ISIL terrorist groups which took over territory in north Mali following the 2012 Tuareg rebellion there.

Since then, the violence has spread into neighbouring countries, Niger and Burkina Faso, and more recently into some other coastal West African nations.

UN Deputy Secretary-General Amina Mohammed characterised the Sahel as “ground zero” for one of the most brutal security crises in the world.

Despite efforts by Member States, terrorism-related deaths in the region have reportedly soared past 6,000 for three consecutive years, making up more than half of all global fatalities.

‘A wake-up call’

Mr. Türk said the “calculated assault” on Fambita Mosque should be a wake-up call to all – including the international community – “as to the seriousness of the situation and the widening risks faced by civilians in Niger.”

Governments in the region have continued to struggle with restoring security. This contributed to two military coups in Mali, two in Burkina Faso and one in Niger between 2020 and 2023 – all remain under military rule despite regional and international pressure to hold elections.

The High Commissioner called on the Nigerien authorities to take “concrete and meaningful steps” to improve security for civilians and called on them to take effective measures to uphold human rights and the rule of law.

He said it was essential that authorities involve the affected communities in efforts towards finding a durable solution to the ongoing human rights crisis in the country.
