Syria Anniversary: Twitter Campaign Urges Tweeps To #UniteForSyria

One year into Syria's uprising and the Assad regime's bloody crackdown, a coalition of 200 NGOs from 27 countries has demanded that the UN Security Council pass a resolution calling on the government to end the torture, arbitrary arrests, shelling of civilian neighborhoods, and other violations of international law.

A Twitter campaign aimed at stopping the bloodshed and drawing attention to the crisis in Syria has urged people to take photos of themselves holding up hand-written signs demanding an end to the violence.

In February, Russia and China vetoed a UN Security Council resolution backing the Arab League's plan for Bashar Assad to step down. US Ambassador Susan Rice said that she was "disgusted" by the veto, according to Reuters.

Among the coalition's list of demands is an urgent UN Security Council resolution calling for an end to the violence.

You can join the campaign by tweeting a photo of yourself asking the UN to pass a resolution using the hashtag #UniteForSyria. Check out the campaign's Facebook page for more photos.
