"Nevertheless, people are alarmed about the lack of advice or information from the government. Well, the policy of the government is quite clear on the matter, we are urging to people to keep calm, use their common sense and to go about their business as normal. Panic can only make matters worse. We all know the situation is serious but we are in constant touch with our allies in Washington and have firm assurance that it's under control. [...] proceed smoothly. Thank you Minister, and we've just had a newsflash from Bonn, that the Russians have cut the road links into and out of West Berlin. Radio and air communications with the city have apparently also been severed. Details are still coming in, but it seems an American army convoy bound for West Berlin has been turned back at on the East German border. Unconfirmed reports say the Russians have offered a safe passage out of the city to the U.S., British and French garrisons. It's not clear if this move is connected with yesterday's riots in East Germany. We'll bring you more details on the story as soon as we have them."
