A man runs after he tried to put himself on fire during a protest at a makeshift camp at the Greek-Macedonian border near the village of Idomeni on March 22, 2016. Greece will not be able to start sending refugees back to Turkey from March 20, 2016, the government said, as the country struggles to implement a key deal aimed at easing Europe's migrant crisis. The numbers are daunting: officials said as of Saturday there were 47,500 migrants in Greece, including 8,200 on the islands and 10,500 massed at the Idomeni camp on the Macedonian border.

“The ONE Campaign is a international, nonpartisan, non-profit organization which aims to increase government funding for and effectiveness of international aid programs. ONE was originally founded by a coalition of 11 non-profit humanitarian and advocacy organizations — including DATA, World Vision, Oxfam America, and Bread for the World — with funding from the Bill & Melinda Gates Foundation. In 2007, ONE announced that it would be merging with DATA. Currently, ONE is campaigning for resources to help developing countries adapt to climate change. During the 2008 U.S. presidential election the organization launched a campaign, called ONE Vote '08, which was co-chaired by former U.S. Senate majority leaders Tom Daschle (D-SD) and Bill Frist (R-TN). The campaign is named after the U2 song “One” which was a top ten hit single on the critically acclaimed 1991 Achtung Baby album”. – Wikipedia
