Aleppo was once the financial capital of Syria, but it has been gripped by fighting since the country spiraled into war five years ago. Activists are calling on Facebook users around the world to change their profile pictures into red image to shed light on the violence in Aleppo, Syria that has claimed the lives of hundreds of thousands of people.

The hashtag #‎MakeFacebookRed spread to urge Facebook users to change the profile picture into red image to raise awareness of the humanitarian catastrophe in Syria and highlight the bloodshed in Syria especially in Aleppo.

The call comes as a second medical facility was hit this week by airstrikes in Aleppo and at least 200 people have been killed in renewed fighting in the ravaged city.

It’s not just Facebook, People did it on Twitter too

The calls for spreading reddish profile pictures did not stop at Facebook, It spread in Twitter too as tweeps changed their profile picture into red to show sympathy and solidarity with Aleppo cause.

Two hashtags launched in Arabic and English (#حلب_تحترق /#AleppoIsBurning) to support the social media marketing campaign that aim to spread awareness about Aleppo.
