Houston, May 7 : Nine people were killed, including the shooter, and seven others wounded in a shooting at an outlet mall in south-central US state Texas, authorities said.

The alleged gunman, who died after a confrontation with police, was among the seven people who were killed at the Allen Premium Outlets, the scene of the shooting, Allen Police Department officials said. Nine additional people were transferred to hospitals, where two later died, officials said. The hospitalized victims ages range from 5 to 61 years old, authorities said.

Multiple law enforcement agencies responded at about 3:30 p.m. on Saturday to the outlets in the Dallas suburb, where an active shooter incident had been reported.

"This is a tragedy. People will be looking for answers," Allen Police Chief Brian Harvey said during a press briefing. "We're sorry that those families are experiencing that loss."
