Two people have been injured as thousands tested their bravery and speed by dashing alongside six fighting bulls in the fourth bull run of Pamplona's San Fermin festival.

The San Fermin press office said there were no gorings in the morning run, but one person was treated in hospital with an elbow injury while another was treated for a similar injury on the street after the event.

Four people - a Briton, two Americans and an Australian - have been gored since this year's runs started on Tuesday. All but the Australian have since been released from hospital in Pamplona.

The nationally televised run sees people racing with six bulls along a narrow 930-yard course from a holding pen to the city's bullring. Today's dash lasted two minutes, 24 seconds.

The bulls are killed by professional matadors in bullfights each afternoon during the festival.

The nine-day fiesta, which features 24-hour street partying, was made famous in Ernest Hemingway's 1926 novel The Sun Also Rises, and draws thousands of foreign tourists.

Bull runs are a traditional part of summer festivals across Spain, and dozens of people are injured each year, mostly in falls.

Two men died recently after being gored by bulls in festivals - one last Saturday in the eastern town of Grao de Castellon and another on June 24 in the south-western town of Coria.

Fifteen people have died from gorings in Pamplona since record-keeping began in 1924 for the San Fermin festival.
