German forces have invaded the Soviet Union.
In a pre-dawn offensive, German troops pushed into the USSR from the south and west, with a third force making their way from the north towards Leningrad.
At 0500 GMT, an hour after the invasion began, the Nazi Minister for Propaganda, Joseph Goebbels, went on national radio to read a proclamation by Adolf Hitler promising that the mobilisation of the German army would be the "greatest the world has ever seen".

Germany is thought to have committed a massive force of more than three million men, supported by more than 3,000 tanks, 7,000 guns and nearly 3,000 aircraft.
They are nonetheless vastly outnumbered by the Red Army which has about nine million men under arms with another 500,000 in reserve.
