Russia is threatening stop American families from adopting Russian orphans after a Tennessee family sent its adopted Russian son back to Moscow unaccompanied, save for a written letter. "Russia threatened to suspend all child adoptions by U.S. families Friday after a 7-year-old boy adopted by a woman from Tennessee was sent alone on a one-way flight back to Moscow with a note saying he was violent and had severe psychological problems. The boy, Artyom Savelyev, was put on a plane by his adopted grandmother, Nancy Hansen of Shelbyville. 'He drew a picture of our house burning down and he'll tell anybody that he's going to burn our house down with us in it,' she told The Associated Press in a telephone interview. 'It got to be where you feared for your safety. It was terrible.'" Russian Foreign Minister Sergey Lavrov called the actions by the grandmother 'the last straw' in a string of U.S. adoptions gone wrong, including three in which Russian children had died in the U.S."
