UK defence secretary Liam Fox has told BBC Radio 5 that targeting Gaddafi himself - something the United States has thus far denied doing - could "potentially be a possibility" if civilians would not be harmed. 

Robert Gates, the US defence secretary, responded negatively to Fox's comments. He said expanding the coalition's goals could divide it and that it was "unwise" to set such specific goals that might be unachievable.
