A New Year's Eve fireworks show in Brussels, Belgium, was canceled by authorities Wednesday amid a threat of an extremist attack.
Tens of thousands of people were expected to turn out to watch the fireworks and ring in the new year at the city square. But according to state broadcaster RTBF, the city's mayor decided to call it off citing safety concerns.
On Tuesday, authorities arrested two men accused of plotting attacks against police and military personnel during holiday celebrations.
According to The New York Times, investigators say they found evidence of threats to several popular Brussels locations that were "in the same style" as the Nov. 13 Paris attacks. Officials also say they seized military-style training uniforms, computer equipment and ISIS propaganda.
