(COLOMBO, LANKAPUVATH) – A gunman has killed 10 people, including a police officer, following an hours-long stand-off at a grocery market in the US state of Colorado.
The attack in Boulder ended with police detaining an injured suspect at the King Soopers market.
The shooting was live-streamed by witnesses and broadcast on YouTube.
Among the dead was 51-year-old Eric Talley, who was the first police officer to respond to the shooting.
“This is a tragedy and a nightmare for Boulder County,” the area’s district attorney, Michael Dougherty, said.
“These were people going about their day, doing their shopping. I promise the victims and the people of the state of Colorado that we will secure justice.”
No other details have been released about the nine other victims or a motive for the attack.
The grocery store is located in a busy shopping plaza in Boulder, a north-central Colorado city about 30 miles (50km) away from the state capital of Denver.
The supermarket attack comes less than a week after a mass shooting that left eight dead, including six Asian women, at three spas in Atlanta.
