According to the Washignton Post:
Gunmen stormed a luxury hotel in Mali’s capital on Friday with 170 guests and staff, killing at least three people and taking hostages in a city that serves as a logistics hub for French and American forces helping fight Islamist insurgents.
There was no immediate claim of responsibility, and the identities or affiliation of the assailants were not clear. But Mali has faced repeated attacks from militants linked to al-Qaeda and other factions.
Security forces conducted room-by-room searches amid sporadic gunfire. U.S. military units and French commandos were dispatched to the scene.
The group Al Qaeda in West Africa is claiming responsibility. You can read about them here. Whether it’s Al Qaeda, ISIS, or Palestinian terrorists, it seems as if they sense an opportunity and are seizing upon it.
