Independence Day is a nationwide patriotic event. The Declaration of Independence was adopted by the Continental Congress on July 4, 1776. The historical document confirmed that Britain's colonies in North America declared themselves as a new nation and did not belong to the British Empire. Since then, the holiday is commonly marked by spectacular fireworks and patriotic marches.

The red alert was announced on that day. 5,000 policemen were assigned to patrol the East River embankment. The authorities reinforced security measures in the wake of the explosion in Central Park of New York on the day before the holiday. Importantly, officials highlight that an accident is not considered a terror attack.
