(CNN) Eleven people died Monday after a Greek air force F-16 jet crashed at a base in Los Llanos in southeastern Spain, authorities said.

Nine were French military personnel, and two were Greek pilots, a senior Spanish defense official told CNN.

The jet crashed on takeoff, hitting other planes on the ground during a NATO training exercise, said the source, who by custom was not named.

Twenty people were injured, according to a statement from the Spanish Defense Ministry. All those hurt are either French or Italian.

NATO Secretary General Jens Stoltenberg said he was "deeply saddened" by the crash.
