This is a fantastic picture. It’s come from the protests in Egypt and is being described as Christians protecting Muslims while they pray during the protests.
Coptic Christians make up about 10% of Egypt’s population and there’s been suggetsions they have much to fear from revolution – if an extreme Islamic faction takes control of Egypt then some worry about the fate of the Coptic Orthodox Church. However, one of the aspects of the current protests in Egypt is how non-religious they’ve been. This is Egyptian brother and sister standing beside Egyptian brother and sister.

As a Muslim, I love this picture and we respect everyone's religious beliefs.
