A quick look at Reuters' web site turns up nothing about their Photoshop Phiasco. In fact, in searching their photos with the search string "beirut", one can still find the doctored photo. Hit this link, and select the photo described as "Smoke billows from burning buildings destroyed during an overnight Israeli air raid on Beirut's suburbs".
Update at 10:39 on 6 August: This story's obviously generated a lot of interest. Poor Charles over at Little Green Footballs is probably having a hard time getting stuff posted today as his server's getting hammered pretty hard.
Update at 11:40 on 6 August: Heh. Now the above linked entry still shows up in the search, but the photo is gone.
