Nothing like speculation, citing Algerian sources:
A rapid intervention unit composed of French, British, Italian and Spanish special forces has been formed to target al-Qaeda in the Sahel countries. Algeria has also formed special units designed to track down and target Al-Qaeda as well as the Tawhid and Jihad group.

I have always considered Algeria the key nation regarding the use of coercion in the Sahel, including Mali.

The other four nations have interests, capability and IMHO insufficient political will to deploy - kidnapping / hostage rescue excepted.
