It's not an extensive list, but BBC and the Guardian (both UK media) have been covering this event as well. http://www.guardian.co.uk/world/2012/mar/20/trayvon-martin-death-story-so-far?newsfeed=true and http://www.bbc.co.uk/news/world-us-canada-17452878 as well as a couple Australian and Canadian press have put out articles as well as the federal government started to get involved. (although I'm loathe to post these gaudy and long links and start to overload this)
