BBC aired a report last week, in reference to the UN's Security Council, and the screens behind presenter Sophie Raworth showed a large graphic. This graphic was the UNSC icon, but had nothing to do with the Security Council, because it was the badge of the United Nations Space Command, the military agency featured in Halo.

You can see, a quick Google image search would be mistaken for Halo's UNSC. UNSC can mean United Nations Security Council, or alternatively in the Halo world, the United Nations Space Command. Viewers spotted the error quickly, and the icon was replaced in later editions of the bulletin.

A spokesperson said:

BBC News makes every effort to ensure the accuracy of all images broadcast. However, very occasionally mistakes do happen. Unfortunately an incorrect logo was used during a segment on last week's News at Once bulletin and we apologise to viewers for the mistake.

Master Chief would be proud.
