France's President Emmanuel Macron celebrated Sunday Bastille Day with a traditional military parade.
About 4,300 soldiers, 196 vehicles, 237 horses, 69 airplanes and 39 helicopters from the 10 countries taking part in the European Intervention Initiative (EII) participated in the parade.
Macron began the ceremony by reviewing the parade along the Champs-Elysees, where he was booed by several onlookers.
Guests of honor included German Chancellor Angela Merkel, British Cabinet Minister David Lidington and Spanish Defense Minister Margarita Robles, all of whom joined in the celebrations and were scheduled to meet with Macron later at the Elysee Palace.
Macron launched the EII in 2018 with an aim to boost the ability of the member countries to act together on missions.
The presence of troops from Spain, Germany, and Portugal among others highlights the member countries' joint will to intervene militarily in any emergency.
Units from the Spanish Armed Forces took part in the parade for the first time.
On Saturday, Macron described the joint parade as a "good symbol" of the development of Euro defense.
The French military showcased some of the latest technologies available to its troops from drones to flyboards, which can reach speeds up to 190 kilometers an hour and run for about 10 minutes. EFE-EPA
