ROME — A mob of S.S. Lazio ultras ambushed 70 Real Sociedad fans in Monti Wednesday night, leaving one Spaniard in critical condition, judicial sources said. 

 A 3-1 win over Real Sociedad, a historically leftist Basque Country club, at the Stadio Olimpico Thursday moved Lazio to the Europa League's elimination quarterfinals. 

 On the eve of the game a mob of hooded Laziali ultras stormed Via Leonina's Finnegan Irish Pub, police said, before driving the group of Real Sociedad supporters down the Leonina. Three Basque fans suffered stab wounds, Football España reported. The ultras injured nine Real Sociedad supporters, all between 20 and 30 years old. Italian judicial sources said three Spaniards were discharged from hospital early the morning of the game, and two remain in care. 

 Rome special operations and investigations forces (Digos) said an investigation was ongoing.
