Russian politicians have agreed a declaration which blames the Soviet dictator Joseph Stalin for
personally
ordering the Katyn massacre, in which thousands of captured Polish officers were shot by Soviet forces during the Second World War. The speaker of the Polish parliament said the move would help the foreign relations between the countries ahead of a visit to Poland next month by the Russian president. From Moscow, Richard Galpin.
A senior member of the Russian parliament described the resolution as a historic document, not just for relations with Poland, but also for Russia itself as it fights what he called the "falsification of history".
For 50 years, Soviet leaders blamed the Nazis for the Katyn massacre.
It was only in 1990 that Mikhail Gorbachev admitted the Soviet secret police had been responsible.
The United States has begun a diplomatic
initiative
to warn foreign governments about another potentially embarrassing release of documents by the whistle-blowing website Wikileaks. The organisation is planning to publish thousands of US State Department diplomatic cables. Steve Kingstone reports from Washington.
Wikileaks has not said when it will make these documents public, but the American government clearly believes the release is
imminent
and is preparing for the worst.
Around the world, its embassies have been contacting other governments to give advance warning amid concerns that the diplomatic cables contain frank, private opinions and perhaps details of State Department sources within foreign governments.
