UK forces 'could be in action by Friday' 17 Mar 2011 UK forces could be in action over Libya as early as Friday, after the UN backed a no-fly zone and "all necessary measures" to protect [?!?] civilians. A senior UK government source has told the BBC action could take longer, but would be within days of the vote. The resolution rules out a foreign occupation force in any part of Libya. Foreign Secretary William Hague said the UK would "now respond" to the responsibility it placed on UN members.
