The attack at midday Friday triggered an hours-long gunbattle and standoff with police in Colorado Springs, leaving one police officer and two other victims dead. Nine others were wounded.

57-year-old Robert Lewis Dear from South Carolina then surrendered to the police. Tightening gun control in the US is always a controversial issue among American politicians.

Following a shooting at a school in Connecticut in 2012 claiming the lives of 28 people including 20 children, President Obama first made the proposal but he failed.
