The Rome-based Il Messaggero newspaper reported that the bomb consisted of a cylinder of gunpower, with shrapnel embedded and electric wires. 

Investigators determined the car belonged to Marco Andrea Doria, president of the board for the redevelopment of parks and historic villas in Rome. 

It was unclear if the car bomb had any connection to the tournament. 

Rome Mayor Virginia Raggi noted the seriousness of the situation, writing on Twitter that she was in "solidarity" with Doria.
