"Following NSC on Tuesday and discussions with the French, we have now decided to deploy Sentinel, a surveillance capability that has proved its worth in Libya and on an ongoing basis for counter-insurgency operations in Afghanistan.
"We have also agreed to continue to make available a C-17 heavy lift transport aircraft which has already provided important logistical support over recent days."
Officer Commanding 5 (AC) Squadron, Wing Commander Al Marshall, said: "Sentinel is deploying to provide a unique intelligence capability in support of French operations within Mali.
