People across the globe are tweeting messages of support for a police dog killed this morning during a police raid in Paris.

The hashtag #JeSuisChien — “I Am Dog” in French — has been trending since the Police Nationale Twitter account confirmed the death of a 7-year-old Belgian Malinois named Diesel.

Diesel was part of the French Research, Assistance, Intervention and Deterrence unit, and he was participating in a raid on an apartment in a Paris suburb where Abdelhamid Abaaoud, the mastermind of Friday’s terrorist attacks, was believed to be hiding.

The dog was sent to the apartment ahead of officers, where police say he was shot and killed by terrorists.

At least five police officers suffered minor injuries during the raid after a woman detonated a vest of explosives.

A male and female suspect were killed during the six-hour operation, and seven people were arrested.

However, while thousands of people have tweeted about the loss of Diesel — often referred to as “the Jack Bauer of dogs” after a character on the TV show “24” — not everyone thinks the #JeSuisChien is appropriate.

Critics have taken to social media to argue that the hashtag detracts from the loss of human lives, especially those of Syrian refugees and those who died during the recent attacks.
