Roma devastata e ferita. In contatto con Prefetto, Questore e Ambasciatore d'Olanda. Non finisce qui #RomaFeyenoord— Ignazio Marino (@ignaziomarino) 19 февраля 2015
"I am seriously angry. What is happening is unacceptable. We are in contact with the authorities and the Dutch Ambassador. It will not end here. I protested and demanded an explanation from those who are responsible for public order in this city," he added.
The Dutch embassy in Rome said in a statement that there was "no place for violence in football" and that it would work together with Italian authorities to punish those responsible.
Italian Prime Minister Matteo Renzo said in a TV interview that he appreciated the message of the Dutch embassy and would take the issue to European football authorities.
Rome’s public works department said its staff was sent to clean the recently restored Barcaccia fountain. Technicians will now assess what damage has been done to it.
On Friday, Italian opposition leaders demanded to remove from post country's Interior Minister Angelino Alfano amid the violent clashes. According to Roberto Calderolli, a leading member of the Northern League, if public order in central Rome can be violated by a group of drunk vandals, those responsible for maintaining it should leave office.
