Heads have been rolling in the Algerian army, the North African nation's most respected institution, and in other security services, with generals in top posts fired - without explanation - at a rate never before seen.

The changes are especially dramatic in a country with the best-equipped military in North Africa and the Sahel that has honed its skills in fighting Islamic extremists. Today, Algeria is a bulwark against extremism for the West.
