Instagram, Facebook and WhatsApp down in parts of UK, USA
Several people have reported issues with Instagram, Facebook and WhatsApp - which are all owned by Facebook.
They're some of the most popular social media apps in the world, but it seems that the apps all crashed this afternoon, The UK Mirror reports.
According to DownDetector, the issues started at around 14:49 BST, and are affecting users across the UK and parts of the US.
The reason for the outage remains unclear, although 82% of those who reported problems with Instagram said the issue was with the News Feed, 11% with the website, and 6% with log-in.
Facebook, which owns the three sites, is yet to comment on the issue.
Many users have taken to Twitter to vent their frustrations at the outage.
