taken between 5 February 2009 and 19 April 2009 was leaked to the media. The images showed numerous craters caused by shelling. The main finding of the report was that "there are new indications of building destruction and damages resulting from shelling and possible air-strikes". The report found that 60 main buildings had been destroyed to date in the Safe Zone but this excluded temporary structures erected by the IDPs as it was not possible to identify damage to these using satellite images. Over 5,000 IDP shelters had also been relocated during April 2009 due to the shelling and bombardment. There was evidence of hundreds of craters and heavy damage to buildings outside the Safe Zone. The report concluded that damage estimates were a minimum and that the "actual damages are likely to be greater". The accuracy of some of the damage suggested that it could only have been done by air-dropped bombs. Although the report does not apportion blame, given that Tamil Tigers' air wing had been destroyed in early 2009, this damage could only have been caused by the Sri Lankan Air Force. After being confronted with the UN satellite images during an interview with Al Jazeera Sri Lankan Foreign Secretary Palitha Kohona admitted that the Sri Lankan armed forces had carried out shelling and air raids in the Safe Zone. This contradicted the statements by the Sri Lankan government and President Rajapaksa, and an earlier statement by Kohona himself, that there was no shelling by the Sri Lankan armed forces in the Safe Zone. Following a request from Amnesty International and Human Rights Watch the American Association for the Advancement of Science compared commercial high-resolution satellite images of the Safe Zone taken on 6 May 2009 and 10 May 2009 to evaluate the impact of heavy fighting on 9/10 May. They found evidence of significant removal of IDP shelters, artillery and mortar emplacements, destroyed permanent structures, bomb shell impact craters and 1,346 individual graves. By calculating the trajectory of the shells which caused the craters the AAAS was able to conclude that the shells likely came from Sri Lankan Army territory. US government satellites had been monitoring the war zone secretly. In April 2009 the US State Department released two satellite images of the Safe Zone showing 100,000 civilians trapped in area. The State Department report to Congress (above) included a number of images taken by US
