I think it's possible that Reuters played with the brightness on this one. But I don't think it's quite accurate to say that it was actually doctored. Because of glare, etc. it's not unusual to alter brightness before publishing a photo. It is possible that due to the glare of the sun this is the way it actually appeared and darkening it would have made everything look black.
The marquis of Nasrallah on the side of the building is pretty dark compared to the rest of the photograph. I'm still a novice in Photoshop, but it looks to me as if the contrast was pumped up so Nasrallah's face wasn't in the dark. It resulted in washing out the rest of the image.
As to the words hanging in the sky, I'd assumed they were letters on posts. You don't see them often in the US anymore but they're still around.
