Polish President Lech Kaczynski and scores of others have been killed in a plane crash in Russia. Polish and Russian officials said no-one had survived after the plane apparently hit trees as it approached Smolensk's airport in thick fog. Poland's army chief, central bank governor, MPs and leading historians were among more than 80 passengers.
They were flying in from Warsaw to mark 70 years since the Katyn massacre of thousands of Poles by Soviet forces.
