A plane carrying Polish President Lech Kaczynski has crashed near a Russian airport, officials say.
Russian media reported that 87 people were killed in the crash near Smolensk, and a regional governor was quoted as saying there were no survivors.
Polish officials said Mr Kaczynski was on board along with his wife Maria and several senior government figures.
They were in Russia to mark the 70th anniversary of the Katyn massacre, when Soviets killed thousands of Poles.
The Russian emergencies ministry told Itar-Tass news agency the plane crashed at 1056 Moscow time (0656 GMT).
