“Islamist militants have advanced further into eastern Mali in recent days, seizing territory, killing hundreds of civilians and forcing thousands to flee, regional Malian officials and analysts said. The gains by the militants highlight Mali's struggle to fill the vacuum following the departure of French and other European forces, while relations with neighbouring Niger have deteriorated, preventing joint military operations near the Niger and Burkina Faso borders. Heavy fighting between Tuareg separatists and the Islamic State in the Greater Sahara (ISGS) group has been reported in Menaka region, where Malian forces took over a French military camp in June. read more While the offensive started in March, France's pullout "left a vacuum and lifted a lot of pressure", said Heni Nsaiba, senior researcher at the Armed Conflict Location & Event Data Project (ACLED), a U.S.-based crisis monitoring group. Hundreds have been killed since March, mainly civilians, as jihadists have battled their way into Menaka and the neighbouring Gao region, according to ACLED data, Nsaiba added. Islamic State-linked fighters are the major perpetrators of that violence, according to the U.N. Secretary General's report to the Security Council released on Thursday. This month, Islamist militants took over the rural Ansongo district, near the border with Niger, a local official and pro-government militia said.”
