Two topless activists from the notorious Femen movement were detained by French police after approaching US President Donald Trump's motorcade along the Champs Elysees in Paris amid events marking the 100th anniversary of the end of World War I.
The protesters came within a few metres of the cortege, screaming indistinctly shortly after French media reported that about 2,000 police officers had been deployed to ensure security at the Champs Elysee celebrations.
The incident comes just a day after three Femen activists showed up under the Arc de Triomphe to protest against "war criminals."
In a parallel development, world leaders are arriving at the Arc de Triomphe for an official ceremony to commemorate the centennial anniversary of the armistice that ceased fighting during World War I.
Femen is a feminist group that has gained notoriety for organising topless protests across the globe.
