Mali jihadists affiliated to the Islamic State group have taken over a village Menaka.
The Islamist militants seized another village Tidermene on Monday following months of fighting.
Since early last year, Islamic State in the Greater Sahara has launched a major offensive in the area as well as in Gao, another region of northern Mali.
There have been battles with the Al-Qaeda-linked fighters as well as Tuareg former rebels who signed a peace deal in 2015.
