The ice curtain that divides Russia and the US

Two islands in the Bering Straits, one Russian, one American, are barely two miles apart.

Only a few military observation posts remain on the Russian island, but a community of Eskimos lives on the US island.

After the Cold War they hoped to resume regular contact with Russian relatives, but now the chances seem to be fading again.

Humphrey Hawksley has been given rare access to an Eskimo community on the American island of Little Diomede.
