A Greek F-6 fighter jet crashed during a NATO exercise in Spain on Monday, killing 10 people and wounding at least 21, including as many as six American service members who suffered minor injuries.
The crash happened shortly after takeoff from Los Llanos airbase in Spain. The cause was unclear.
Eight French citizens and two Greeks died in the crash, Spain's defense ministry said. The nationalities of the other wounded people, including some who were seriously hurt, were not immediately known.
The exercise was part of NATO’s Tactical Leadership Program, which aims to improve multinational cooperation in air operations, NATO Secretary General Jens Stoltenberg said in a statement.
"Deeply saddened by the air crash in Spain - a tragedy which affects the whole NATO family," Stoltenberg said on Twitter. "My heartfelt condolences."
