France's Macron booed during Bastille Day parade

STORY: It happened as he drove down the Champs-Elysees in a military car.

His decision to raise the retirement age sparked months of protests this spring and has hurt his popularity ratings.

Bastille Day commemorates the storming of the Bastille prison in 1789, one of the key events of the French Revolution. The day has become a national holiday in France.

This year's guest of honor was Indian Prime Minister Narendra Modi, as part of a visit that has sealed high-profile defense deals.
