Two firebombs were thrown at the offices of Italy’s tax enforcement agency in Livorno on Saturday.
They landed on the doorsteps of the Equitalia building, but nobody was hurt. Police believe anarchists carried out the attack.
It follows a wave of highly publicised suicides in Italy, where the government of Mario Monti has hiked taxes to fight spiralling public debt.
Italy’s Deputy Economy Minister Vittorio Grilli insists the measures being taken are the right ones.
“It’s impossible to think that when the state asks the citizens to pay what they have to pay, it is considered as the enemy,” he told Italian television.
Protesters hung dozens of effigies in Rome this weekend to symbolise the reported surge in suicides.
An Italian business association estimates more than 30 entrepreneurs have taken their own lives since the start of the year.
