Russia is threatening to suspend all adoptions of Russian children by US families after a Tennessee woman sent an adopted seven-year-old boy unaccompanied on a flight back to Moscow.

Artem Saveliev arrived in Russia with a note from the adoptive single mother saying she had made a mistake taking him and does not want him anymore. She claims he was mentally unstable and violent.

But Saveliev said the adoptive mother was abusive.

Russia's foreign minister has called it the 'last straw' in a series of US adoptions that have gone wrong.
