The 7-year-old dog, deployed with security forces as an explosives-detecting K9, was killed while conducting a raid on an apartment in the Parisian suburb of Saint-Denis. Diesel was the first to enter the unit to assess the threat. As she did, a terrorist inside detonated a suicide bomb which sadly claimed the dog's life, French news outlet 20Minutes reports.
No other officers died in the attack, though several were injured during the operations in which two terrorism suspects were killed and seven were arrested.
Shortly after, French National Police announced Diesel's death on Twitter, describing her role as "indispensable."
