A professional bullfighter was gored to death and a man was killed in a bull run in Spain on Saturday, while 13 other people were injured at the world-famous running of the bulls in Pamplona, according to news reports and a government website.

The matador, Victor Barrio, 29, was performing on live television in his first bullfight at Los Maños, a ring in Teruel, a town in eastern Spain, when a bull punctured his lung. He was treated by medical personnel at the scene but was pronounced dead at a hospital, according to the Spanish newspaper El Periódico.

Mr. Barrio began his career as a novillero, or a young bullfighter, in 2010.

His last post on Twitter, on July 4, featured a photo of him practicing with a calf captioned, “mind focused on #Teruel.” He is the first Spanish bullfighter to die in a ring in at least 16 years.

Separately, in Pedreguer, a southeastern village near Valencia, a 28-year-old Spaniard was killed in a bull run, during which people race with the animals through narrow streets.
