Demonstrators hurled firebombs in a march towards the US Embassy in Athens on Wednesday in a protest over the death of George Floyd in Minneapolis.
Reuters journalists saw demonstrators throwing several flaming objects which erupted into flames on the street towards the heavily-guarded embassy in central Athens and police responding with rounds of teargas.
The embassy itself was cordoned off with rows of blue police buses.
Demonstrators were holding banners and placards reading “Black lives matter” and “I can’t breathe”.
Police sources estimated the number of protesters at more than 3,000.
