International adoption has again been thrust into the spotlight, following the story of Artyom Savelyev, an eight-year-old Russian boy, who was sent back to Moscow after his American adoptive mother decided he was too much hard work.

Since the mid-1990s, 16 adopted children have died in the US, most at the hands of their adopted parents. The Kremlin says that Artyom's case is the last straw.

The story has sparked a diplomatic dispute between Moscow and Washington.

Russia's foreign minister said that all adoptions to parents in the US will be frozen until an agreement on the issue is reached.
