Federal prosecutors have asked a judge to limit Boston Marathon bombing suspect Dzhokhar Tsarnaev's (joh-HAHR' tsahr-NEYE'-ehvz) access to gruesome autopsy photos of the three people killed in the attack.

In court documents filed Monday, prosecutors say Tsarnaev should not be allowed to see autopsy photos that will not be used at his trial. They say allowing the man accused of killing them to see photos of their mutilated bodies "would violate the victims' rights to dignity and privacy and subject them to needless harm and suffering."

Prosecutors say they don't want to restrict Tsarnaev's lawyers from seeing any photo. But they do want Tsarnaev to be allowed to see only the autopsy photos that will be used at trial.

Tsarnaev's lawyers did not immediately return calls seeking comment.
