Crowds have protested billionaire Elon Musk’s purge of the U.S. government under President Donald Trump outside Tesla dealerships throughout the U.S. and in some cities in Europe.

The plan for a day of mass demonstrations follows a series of violent incidents. Anti-Musk activists have been accused of throwing Molotov cocktails at Tesla facilities in Colorado, Nevada and Oregon and defacing Tesla vehicles there, and on Monday, authorities said they found multiple “ incendiary devices ” at a Tesla location in Texas.

Hundreds of “Tesla Takedown” demonstrations are taking place in the United States, Canada and Europe as activists ramp up their opposition to CEO Elon Musk’s efforts to slash federal government staffing and budgets.
