A large surprise attack by about 100 Islamic jihadists, driving pickup trucks (technicals) and motorcycles, on a Mali military base, resulted in the deaths of 33 soldiers and the wounding of 14 others. Several other troops are missing. 

The Malian military claims to have killed 20 insurgents.

The jihadist attack took place on Monday in the town of Tessit, located 37 miles southeast of Ansongo, in the violent “Tri-Border Region” of Mali’s border with Burkina Faso and Niger. The area around the three borders has seen the most violence in the troubled Sahel region. 

No group has yet acknowledged the attack. Yet, insurgents aligned with both al-Qaeda and the Islamic State (ISIS) are very active in the region.
