10 killed, including a police officer, in shooting at supermarket in US state of Colorado

The United States is again reeling from a mass shooting, the second in less than a week. A gunman has been taken into custody after killing 10 people in a grocery store in Colorado. He opened fire in Boulder, sending shoppers running for cover. One of the first police officers to arrive at the scene was among those killed. Colorado has suffered two of the most infamous mass shootings in US history -- the killings at Columbine High School in 1999 and the 2012 movie theater shootings in Aurora.
