We know Joan Rivers is never afraid to speak her mind, but this one may have taken things too far. She says the 2000 Palestinian civilians killed in the Gaza conflict "deserve to be dead."

TMZ's cameras caught up with Joan outside LAX yesterday and asked her opinion about the violence between Israel and Hamas. After crying a few crocodile tears, she argued that the civilians who were killed had been warned to leave. She then suggested that their failure to get out of harm's way was evidence of their stupidity, and "at least the ones that were killed were the ones with very low IQs."

The last time Joan was under fire was in May, when she suggested that the three Cleveland kidnapping victims had more space than her daughter Melissa's guest room.
