UPDATE: The BBC has responded to its broadcast of a Halo logo during Thursday's News at One, admitting its mistake and apologising to viewers.
A BBC spokesperson told Eurogamer: "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 One bulletin and we apologise to viewers for the mistake.
"The image was not broadcast in our later bulletins."
ORIGINAL STORY: BBC News has accidentally broadcast a logo from Halo during a news report on the ongoing conflict in Syria.
The blooper occured in the background of last Thursday's One O'Clock News, in which presenter Sophie Raworth discussed the real-life United Nations.
But the logo shown on-sceen was for the UNSC - Halo's fictitious United Nations Space Command.
Facebook user Luke Mair nabbed an image of the error when rewatching the programme via BBC iPlayer. The programme has since become unavailable to watch due to the BBC's standard day limits.
A YouTube clip of the error has surfaced online:
