Dozens of people were trampled at Pamplona bull run in Spain on Saturday when they were trapped at the narrow entrance to the bullring with the bulls that had been chasing them through the streets.
The sheer number of runners trying to enter the ring forced shut a door that was usually left open. Runners and bulls were trapped together in the bottleneck for almost two minutes.
At least 23 people were treated in hospital afterwards.
A Spaniard was in a "very serious" condition, a man from Ireland had chest injuries and an American was gored in the buttocks. A Spanish teenager was gored in the armpit.
Three men were gored during Friday's run, including an American tourist who had to have his spleen removed.
The Pamplona run takes place at 8am every day for one week in July. Saturday's run lasted 4 minutes and 15 seconds. Sunday is the last day.
Fourteen men have died in the last 100 years in the run at the San Fermin festival, which dates from the 13th century.
