The Austrian foreign ministry says a female citizen has been taken by unknown assailants in the military-ran West African country, Niger.

It confirmed the incident to AFP and said they were aware of the "possible kidnapping of an Austrian woman" in Agadez which is 900 km (559 miles) from the capital Niamey.

The woman was reportedly forced into a 4x4 vehicle by unidentified individuals in the Fada district, Agadez, on the edge of the Sahara Desert, reported Reuters news agency.

The victim, named Eva Gretzmacher, is a development worker in her mid-70s and had lived in Niger for over two decades, according to the local media site, Air Info Agadez.

Niger has not yet commented on the incident.

Air Info reported kidnappers showed up at Ms Gretzmacher's house with a gun and forced their way in. They did not take anything else, reports said.

Ms Gretzmacher is said to have run projects in the areas of education, health, women's empowerment and culture.

The Austrian foreign ministry said they are working with the EU delegation and authorities on the ground.

Niger has been battling an Islamist insurgency for years.

The military junta is under pressure for failing to curb militant attacks, one of its justifications for deposing democratically elected President Mohamed Bazoum in July 2023.

Niger, along with its neighbours Mali and Burkina Faso, is grappling with attacks from groups linked to al-Qaeda and ISIS.

Since the coup, Niger has urged France and other Western powers to withdraw their military bases and formed a security alliance with junta-led neighbours Mali and Burkina Faso.
