The BBC apologized Sunday for broadcasting a racist slur in a news report, saying it was a mistake that has caused many people distress. The BBC included the word when reporting last month on a violent attack on a young Black man in Bristol, a city in southwest England. The attackers are reported to have yelled the offensive term as they ran into the 21-year-old with a car. The victim needed hospital treatment for a broken leg and other injuries. The broadcaster has received more than 18,000 complaints about the use of the offensive word.
