A weird phenomenon has been noticed in recent social networks ... We do not know exactly whether you've found it, but the situation is this: many Instagram users and Facebook have changed their profile pictures, turning them back they simply on a blue background and this for a very unique and meaningful purpose.

Choosing to put a blue photo on a personal profile in social media comes as an expression of solidarity with Sudanese protesters, where after a brutal and surprise blow there were dozens of people killed. The attack occurred in the capital Khartoum and was one of the events that has faded on the world media.

Hashtag: #blueforsudan

The Sudanese army is trying to prevent the spread of a massacre among civilian protesters, but despite the closure of the internet, the word is spreading massively. To draw attention, people in the social media are turning their blues profiles together with the hashtag #blueforSudan.

The blue color was chosen by friends of Mohamed Mattar, the 26-year-old who was killed during the attack by security forces in Sudan earlier this month. Blue was his favorite color. He was shot while trying to protect two women during the bloody assault on the protest outside the military headquarters.

This campaign is receiving world attention thanks to the influence of Shahd Khidir, a Sudanese influencer of Instagram and a blogger of beauty based in New York. In a post on Instagram with a blue image of the profile, Khidir told tens of thousands of followers about her friend's murder and campaign, expressing that she wanted the voices of protesters to be heard in the face of Sudan's Internet interruption.
