On August 4, 2006, 17 employees of our organisation were killed in cold blood while assisting the population suffering from the consequences of the tsunami and the confl ict in Sri Lanka. This massacre – amounting to a war crime – is unprecedented in the humanitarian fi eld. At the time of the events, the town of Muttur was the scene of heavy fi ghting between rebels and government forces, causing dozens of civilian deaths. However, the victims were clearly identifi ed as humanitarian workers.
