The customary march marking the anniversary of the 1973 Polytechnic uprising arrived outside the U.S. embassy in Athens on Tuesday, where participants commemorated 42 years since the student revolt by singing the national anthem while holding the Greek flag.

The US embassy was heavily guarded following the terrorist attacks in Paris on Friday. Police deployed around 6,000 officers to ensure the safety of the rally.

Out of respect of the victims of the Paris attacks, a group of youths paused outside the the French embassy in central Athens to pay their respects to the victims of the terrorist attacks.
