Correction: The Raw Story tonight posted that the video that was claimed to be of an Israeli attack appears to have been in error. The footage was actually taken on September 23, 2005 at the Jabalya refugee camp, described as a bombing of a parade that killed at least 15 Palestinians. Israel denied responsibility, and the ruling Palestinian Fatah blamed Hamas.
Normally, The Raw Story is very good about their reporting, but apparently they were duped by a false attribution. As bad as the tragedy and the video of it was, I'm at least somewhat relieved it didn't happen as a result of the current incursion.
But today's reports of the Israelis possibly using cluster munitions in populated civilian areas is very disturbing. I think I'll probably wait until there's a video with a "CNN" logo in the corner before I post it, however.
