Clashes between football fans and authorities at the weekend's Rome derby left 24 police officers injured, with the city's mayor comparing the violence to "urban warfare".
Supporters attacked police in riot gear near the Stadio Olimpico hours before the Serie A match between Lazio and Roma kicked off at 8:45 pm on Sunday. One arrest was made, and at least €40,000 worth of garbage dumpsters were damaged, local authorities said.
