A young turtle from a Canadian children's book series is caught in an international feud after the US Defence Department used the character in a cartoon about killing alleged drug traffickers.

The publisher of "Franklin the Turtle" books is criticising Secretary of Defence Pete Hegseth for a social media post depicting the beloved children's character shooting the alleged criminals.

"We strongly condemn any denigrating, violent, or unauthorised use of Franklin's name or image", publisher Kids Can Press said.

The publisher is not alone. Sabrina Carpenter lashed out at the White House on Tuesday for using her song in a video about deporting migrants, saying it was "evil and disgusting".

"Do not ever involve me or my music to benefit your inhumane agenda," the singer posted.

In Franklin's case, the cartoon posted by Hegseth on social media is a mock book cover depicting Franklin in a military helicopter firing a large weapon at alleged drug boats. The faux title reads: "Franklin Targets Narco Terrorists."

The image comes amid a string of US strikes on alleged Venezuelan drug boats since early September. The Trump administration says it is acting in self-defence by attacking boats carrying illicit drugs to the US.

Hegseth captioned the post: "For your Christmas wish list..."

Franklin, the 6-year-old cartoon turtle, is known for navigating everyday challenges, from learning to ride a bike to having his first sleepover.

He originated as the titular character in the Canadian children's book "Franklin the Turtle" and has grown to star in a number of television shows, films, video games and live productions.

"Franklin the Turtle is a beloved Canadian icon who has inspired generations of children and stands for kindness, empathy, and inclusivity," publisher Kids Can Press said in its statement, adding that such a violent depiction "directly contradicts these values".

Chief Pentagon spokesperson Sean Parnell said in a statement on Monday night that "We doubt Franklin the Turtle wants to be inclusive of drug cartels... or laud the kindness and empathy of narco-terrorists".

The artists credited with creating Franklin and authoring his books did not respond to requests from the BBC for comment.

In September, Pokémon said it did not give permission for the use of its theme song and other footage to be used in an ICE deportation raid video posted by the US government.

British singer Jess Glynne also criticised White House officials in July after they used a viral Jet2holiday advert featuring her song in a video promoting deportations.
