MADRID: An 18-year-old man has died after being gored by a bull in the abdomen was the fourth person killed during a string of deadly weekend bull runs in Spain, authorities said on Monday.

The young man, who was wounded on Sunday during a bull festival in a village near the northern city of Pamplona, died as he was being taken to a hospital, an official from the regional Navarra government told AFP.

His death increased the number to four of people who have been killed since Friday during traditional bull festivals, where crowds of people run ahead of herds of bulls in towns and villages across the country.

In total, at least seven people have lost their lives at bull festivals since the beginning of July, including at least one who was gored in the neck earlier this month while filming the run on his mobile phone.

A number of people were also injured during the annual running of the bulls at Pamplona's famed festival in July.
