London's New Year celebrations proceeded despite severe weather that cancelled events across Britain, while a social media hoax drew thousands to non-existent Birmingham fireworks. Ukraine ended Russian gas transit to EU, marking a shift in European energy dynamics.
The morning's celebratory tone shifted dramatically with reports of a vehicle attack in New Orleans. Initial casualty reports of 10 dead evolved throughout the day as the FBI discovered explosive devices and an ISIS flag at the scene. By evening, the death toll reached 15, and the attacker was identified as US Army veteran Shamsud Din Jabar.
The day concluded with a second vehicle attack at Trump Hotel in Las Vegas, where a Tesla Cybertruck explosion killed one and injured seven. Authorities began investigating connections between the attacks through a shared vehicle rental platform, while Elon Musk speculated about explosives or fireworks as the cause.
