An aunt of the Boston terror suspects has suggested that her two nephews are innocent and have been set up.
Maret Tsarnaeva told media she believed the photo showing Tamerlan and Dzhokhar Tsarnaev at the scene of the Boston Marathon bombing was a fake.
"I am suspicious that the picture was staged. They could not have done this. Where is the evidence?" she said.
When asked who she thought was behind the alleged set-up, the Toronto-based Tsarnaeva replied, "whoever is looking for someone else to be blamed".
Detectives in Boston are looking further afield as they piece together their case against Marathon suspect Dzohkhar Tsarnaev.
The uncle of Boston bombing suspect Tamerlan Tsarnaev described his recent visit to Dagestan in Russia and his great shock at the attacks.
Both men were enrolled in a school in Dagestan, a neighbouring region that was drawn into Chechnya's violence during the 1990s.
