The capture put the fragile Malian Government in a difficult position. After receiving a request to intervene by Mall＇s interim Presi- dent. Dioncounda Traore, France helped to recapture the important town. In the aftermath of the action French drones bombed several rebe military camps and an arms cache, in the process killing more than 100 rebels. France lost an attack helicop ter and a pilot in the attack.展开更多
