From the BBC:
Bulls have gored seven people to death during festivals across Spain since the beginning of July - four of them over the past weekend. The deaths occurred during bull-running in the streets, not in bullrings. It is an unusually high number of fatalities for such a short period...
Last year more than 7,200 bulls and steers (castrated bull calves) were killed by bullfighters across Spain, the news website El Diario reports.
