( CNN ) -- Pictures taken shortly after the raid that killed al Qaeda leader Osama bin Laden show three men lying dead in pools of blood and the wreckage of a U.S. helicopter abandoned during the assault . One of the dead men bears a family resemblance to bin Laden , but there was no confirmation of his identity . The al Qaeda leader 's adult son was among those killed in Monday 's attack by U.S. commandos , according to American officials . The pictures were published Wednesday by Reuters . The news agency says they were taken by a Pakistani security official about an hour after U.S. forces left bin Laden 's compound and that it is confident of the authenticity of the purchased images . Clad in a T-shirt , the man who resembles bin Laden lies in a large pool of blood that appears to spread from the back of his head . Two other men , dressed in Pakistani clothing , appear to have died from extensive head and chest wounds . Sources have named the courier who lived at the compound as al Qaeda veteran Sheikh Abu Ahmad -- a Kuwaiti citizen of Pakistani descent . Other photos , taken at dawn on Monday show the wreckage of the helicopter the U.S. Navy SEAL team had to leave behind after a crash-landing . Analysts believe it to be a stealth aircraft ; the tail assembly is different from known helicopter types and could indicate some kind of previously unknown capability to avoid radar . A senior U.S. official tells CNN that a tail portion of the helicopter was not destroyed , and that , to the best of his knowledge , that wreckage remains in the hands of the Pakistani government . In particular , the tail features a cowling that might have been designed to reduce rotor noise levels , they said . Pakistan has already said that the helicopters used in the raid took advantage of blind spots in radar coverage to penetrate deep into its territory undetected . CNN 's Chris Lawrence contributed to this report .
