US Air Force officials said it was "an honest mistake" to name a "Fun Shoot" event after murdered civil rights leader Martin Luther King.

The officials in Georgia said they were “deeply sorry” for distributing flyers to promote the "Martin Luther King Jr. Fun Shoot" event and have removed them.

The event is still listed on its website, although the name of Martin Luther King has been omitted, as reported by RT.

The adverts said shooters could pay $20 for two rounds and a lunch, with awards for pro and novice categories.

A press release by Robins Air Force base spokesman Roland Leach said the air base would provide “remedial training” for those involved in the poster.
