A man has been killed and nine others injured in a shooting in the historic French Quarter of the US city of New Orleans. Police said the shooter opened fire shortly before 01:40 local time (0740 GMT) on Sunday at the corner of Bourbon and Iberville streets. Police Superintendent Michael Harrison told a news conference the victims were eight men and two women, ages 20 to 37. He said two men had been arrested on firearms charges. Supt. Harrison said police do not know what motivated the shooting and that investigations were ongoing, BBC reported. He added that the Bourbon Street area, which is popular with tourists, had an increased police presence at the time due to the Bayou Classic, an annual college football game taking place the night before at a nearby stadium. New Orleans Police Department had made eight other firearms arrests over the past 24 hours, Harrison said. The man killed in the shooting died in hospital where the other nine victims remain in various conditions. This is the second mass shooting on Bourbon Street in less than three years.
