Supersecret operation, how Poland received the gold bars worth $5 billion from Britain

The vast amount of gold has been transported by helicopters, planes, and high-tech trucks.

Foreign media suggest that numerous police forces have participated in this very important operation.

Eight flights took place at night from an airport in London in recent months.

The country's gold reserves have been preserved in the Bank of England for decades after being evacuated from Poland in the outbreak of World War II, amid fears of falling into Nazi hands.

But Poland's nationalist government has now begun repatriating gold in order to strengthen the country.
