ATHENS — Traffic has been restored in Patission, Stadiou and Panepistimiou avenues in central Athens, police reported on Tuesday evening, while several metro stations remain shut.

The city's center was blocked off to traffic earlier on Tuesday, as pandemic restrictions forbade public crowding for events commemorating Athens Polytechnic Day. Minor clashes between police and people who attempted to break the ban ensued in the afternoon.

Police had announced on Monday that metro stations Omonia, Panepistimiou, Syntagma, Evangelismos, and Megaro Mousikis (Athens Concert Hall) would shut down at 12:00 on Tuesday. Following the clashes downtown, several other stations were also shut down: Metaxourgeio, Monastiraki, Victoria, Attiki, Sepolia and Stathmos Larissis.

Trains are passing through the above stations without stopping, until further notice.
