Four people were hospitalised on Monday on the first day of Spain's San Fermin bull run, a daily race through the narrow, cobbled streets of Pamplona that forms part of the northern city's week-long festival. One runner was gored in the thigh while the other three suffered fractures during the race against five bulls which lasted 2 minutes and 25 seconds, according to the Red Cross.
