(The BBC reported that nearly 12,500 persons had fled in the previous week, 3,000 of them in the previous 24 hours.) Train and auto traffic also was blocked. Protests played out on the streets and through diplomatic channels; nevertheless, the city would remain separated for decades, till the tearing down of the Berlin Wall in November 1989.
