Kuhlood Badawi, an information and media coordinator for OCHA, the UN's Office for the Coordination of Humanitarian Affairs, posted a link to the picture of a young girl covered in blood being carried by her father, along with the tweet: "Palestine is bleeding. Another child killed by #Israel... Another father carrying his child to a Grave in #Gaza."

The picture, it emerged, was published in 2006 by Reuters and was of a Palestinian girl who died in an accident unrelated to Israel.
