Hundreds of people gathered in New York’s Times Square for a flash mob event in support of besieged civilians in Syria.

The public performance, organized by the United Nations Relief and Works Agency (UNRWA), follows a huge social media campaign that engaged over 40 million people on Twitter.

Tens of thousands Palestinian refugees remain trapped in the Yarmouk Syrian camp on the edge of Damascus with very little food or medicine.

Times Square, a major commercial intersection in midtown Manhattan that draws millions of visitors each year, is famous for its electronic billboards.

Alex King was at the event as an image of Palestinian refugees queuing for food was displayed on a massive billboard.
