Images show a picket line in front of UCL hospital in London as junior doctors begin a 3-day strike over pay at the start of a week that will also see teachers, train staff and civil servants walk out in the lastest of a wave of UK industrial action. The strike by junior doctors -- who are not senior specialists but can still have decades of experience -- is the longest they have ever staged. The British Medical Association, the body representing them, says junior doctors have suffered a 26% real-terms paycut since 2008/09 and are demanding a 35% wage hike to combat this. IMAGES
