15 police officers were treated in hospital after an explosive was thrown at them by anti-government protesters in Turin on Friday.

The incident happened after protesters, many of them students, tried to break through a phalanx of officers to reach police headquarters in one of the city’s main piazzas.

Police with batons and shields fought them back.

Protesters also attacked Italy’s national cinema museum, located inside the Mole Antonelliana, a domed building with a tall spire that is the symbol of Turin. Protesters tore down the Italian flag, an act which was condemned by museum staff.
