The image in which President Barack Obama and the British and Danish prime ministers - David Cameron and Helle Thorning-Schmidt, respectively - are seen taking a photo of themselves during the memorial for Nelson Mandela has become one of the most-commented-upon subjects in the U.S. media and across the social networks.

The "selfie" the three leaders made using Thorning-Schmidt's cellphone has sparked all sorts of commentary about whether the behavior was appropriate, given that the trio were at a memorial service.

The moment at which the three took the snapshot was captured by a press photographer, who has said that he thought simply that "they were behaving like human beings."

In the image, Thorning-Schmidt appears in the center, holding up the cellphone, while Obama and Cameron are smiling and leaning toward her to get into the frame of the photo.

Speculation is also circulating about whether first lady Michelle Obama, who appears in the photo on the other side of the president sitting slightly separated from the three leaders and with a serious demeanor, was bothered about her husband's behavior or even jealous.

Commentators and analysts have been repeatedly asked on television to discuss whether it is appropriate or not to snap a "selfie" at a funeral, especially if one is a world leader of Obama's stature.

Cameron, for his part, took the controversy all in good humor and, when asked by a lawmaker about it, said that the photo was taken out of good manners at the request of the Danish leader, since she is the daughter-in-law of former British Labor Party leader Neil Kinnock. EFE
