Westminster Security Incident

5 News: Westminster Terror Attack listed at 18:30

ITV News at 22:00 - 23:00 followed by local news

BBC One at 18:00 - 18:45 followed by full local news bulletin then The One Show.

No changes to Channel 4.

ITV.com have replaced their main banner image (usually a promotion for a show) with a link to ITV News, don't think I've seen that happen previously: http://www.itv.com

5 News also suffered from poor 4G during Tessa Chapman's live.

Goes without saying that this is horrible news, knowing just how busy and full of tourists Westminster Bridge is at any time of day.

Minor thing but I haven't seen it before - on Sky Q the main banner on the home screen (usually showcasing a big new series or movie premiere) is currently linking to Sky News with the words 'Turn to Sky News for an important breaking story'.

BBC News are running a separate live stream on Facebook Live.

I half expected 5 to stay on air for the hour between 5 News at 5 and 5 News Tonight, however Neighbours is on as scheduled.

PA reporting that the stabbed police offer has died. Awful news.

Incidentally, one of the first on-the-scene eyewitnesses on Sky News at the start of the coverage this afternoon was football commentator Alan Parry.

ITV just very briefly cut to the BBC then - with the titles for the six o'clock news

BBC News at Six titles partially played on ITV...

German Das Erste has scheduled a special Brennpunkt following the Tagesschau, which means that football match between Germany and England will begin 10 minutes later.
