Several cities around the world are cutting back or canceling New Year’s Eve celebrations due to safety concerns. Authorities cited risks from terrorism, violent incidents, and large crowds as reasons for the precautionary measures.

In Paris, the planned New Year’s Eve concert on the Champs Élysées was canceled at the request of police. Officials said the area is not safe for large moving crowds, though fireworks at the Arc de Triomphe will still take place, with a prerecorded concert replacing the live show.

Security concerns increased after US authorities said they had stopped a New Year’s Eve bombing plot in Los Angeles. Four suspects were arrested in the Mojave Desert while preparing explosives for coordinated attacks across the city. The suspects have been charged, though Los Angeles officials plan to continue celebrations with tight security in place.

Other cities are taking similar measures. In Sydney, events at Bondi Beach were canceled following a recent terror attack, partly as a show of support for the Jewish community. Tokyo also called off its famous Shibuya countdown to prevent crowd accidents and potential attacks. Belgrade canceled all official celebrations.

Meanwhile, New York City is moving ahead with its Times Square ball drop, which usually draws around one million people. Former NYPD inspector Paul Mauro said the event is heavily policed, with detailed planning to prevent threats and crowd incidents.

Authorities are urging people attending New Year’s events to stay alert, follow security guidance, and plan for crowded conditions as the holiday approaches.
