Six people were gored and eight others have been injured on the second day of the annual bull-running festival in Pamplona, Spain.

More than 1,000 people took to the streets for the second run of the week-long festival.

Just moments into the event, several bulls became separated from the herd, and began charging at people in the crowds.

The Spanish Red Cross said six people had been gored and eight others were taken to hospital for treatment after being injured in the race.

A number of runners, as well as the bulls, repeatedly slipped and fell on the rain-slicked cobbles.
