There have been irregular reports of tye nun’s safety over the years. The columbian police however reported several meetings were held to try to secure her release.

“Meetings have been held worldwide, with ambassadors from several European countries, but also from African countries, always in the spirit of seeking the safe release of our compatriot (Gloria Cecilia Narvaez,),” said Jorge Luis Vargas, Director of the Colombian National Police.

Mali has been trying to contain an Islamic extremist insurgency since 2012.

Extremist rebels were forced from power in Mali’s northern cities with the help of a 2013 French-led military operation.

However, the insurgents quickly regrouped in the desert and began launching frequent attacks on the Malian army and its allies fighting the insurgency.

The extremists have expanded their reach well into central Mali.
