US President Barack Obama: Meaningful action will be taken to prevent more tragediesFriday 14 December 2012 23.58
Wiping away tears and pausing to collect his emotions during a nationally televised appearance, President Barack Obama mourned the "beautiful little kids between the ages of five and ten years old" who were killed at a school shooting in Connecticut.
"As a country we have been through this too many times," Mr Obama said, ticking off a list of recent shootings.
"We're going to have to come together and take meaningful action to prevent more tragedies like this, regardless of the politics," Mr Obama said.
The comment was an apparent reference to the influence of the National Rifle Association over members of Congress.
Mr Obama expressed "overwhelming grief" as a parent, and said he deplored the "heinous" attack by a heavily armed gunman at a school that killed 26 people, including 20 children.
The shooter is also dead, police said.
Mr Obama remains committed to trying to renew a ban on assault weapons, White House spokesman Jay Carney said.
