The killing of Tamils has been mentioned on 'My London Diary' on previous occasions, with a five-day fast in Parliament Square by Thaya Idaikkadar in June 2006 - http://mylondondiary.co.uk/2006/06/jun.htm - and the leafleting by Tamils in Central London last October- http://mylondondiary.co.uk/2008/10/oct.htm#parliament - but little it has appeared in the mainstream media.
Last October I wrote "International media are banned from the Tamil areas of the country and NGOs have been ordered out of some areas, so there are few reports of the war. The Tamils allege that over 100,000 Tamils have been killed, over a million have fled the country and another half million have fled their homes inside Sri Lanka - half of these in the last three months."
