Instagram is filling up with black squares in the latest movement to protest against racial inequality and police brutality.
The simple posts are intended as a way of expressing solidarity with the Black Lives Matter protests that have swept the US after the death of George Floyd.
To join in, users simply post a black square onto their feed – and then commit not to post over the rest of the day. Instructions on how to do so can be found below.
The movement is part of an event called "Blackout Tuesday" that is intended to allow people to consider how best to fight against racism.
What is Blackout Tuesday?
The movement began in the music industry, with a number of leading names committing to commemorate the day by refraining from posting on social media or releasing new content. Instead, the day would be used as a "day to disconnect from work and reconnect with our community" and was organised under the hashtag "#THESHOWMUSTBEPAUSED".
But it has quickly spread across the rest of the internet too, with both major brands and individuals committing to be part of the blackout and use the time to fight against racism.
To show support, all a user needs to do is post a black square onto their feed. People have also been posting messages of solidarity under those images – though the prevalence of the use of the Black Lives Matter hashtag has led some to point out that the protest could actually be obscuring important information.
People are then encouraged to use the rest of their day to give their support to the ongoing protests in other ways, as well as allowing their feed to go quiet so that posts from people of colour can more easily be seen
