This vast region witnessed weeks of violence and clashes between many regular and irregular armed formations, including groups affiliated with Al-Qaeda and the Islamic State.

In its statement Thursday, MINUSMA expressed its "deep concern" about the deterioration of the security situation significantly in recent weeks in the so-called Triangle border area between Mali, Niger and Burkina Faso.

The army responds

For his part, United Nations Secretary-General Antonio Guterres called - in a report submitted to the Security Council this week - the army in Mali and its "partners" to respect their "international obligations" during their counter-terrorism operations.

The Malian army responded in its statement Friday evening that "respect for human rights as well as international humanitarian law remain a priority in the conduct of operations."

The latest United Nations figures show that about 18,000 people have fled to Niger to escape the fighting in northern Mali between the various armed factions.
