At least 10 people were shot dead by a gunman at a grocery store in the western US state of Colorado, police said Monday.

Among those dead was police officer Eric Talley, who was the first to respond to the scene at a King Soopers supermarket in Boulder, near Denver.

"We know of 10 fatalities at the scene, including one of our Boulder PD officers... Officer Tally responded to the scene -- was first on the scene -- and he was fatally shot," said police chief Maris Herold.
