Greek police have arrested at least 5 people during an 'anti-vaccination' protest on Wednesday evening in Syntagma Square, Athens.
According to authorities, some 3,500 protesters gathered in Syntagma Square rejected calls by police to make way for incoming traffic and started throwing bottles and other objects against anti-riot police.
Police proceeded to disperse the crowd with teargas and a water cannon.
Minor incidents also occurred a little earlier at Propylea, where anarchists had also staged a similar protest, police added.
