Calls for tighter gun control in the US after Connecticut tragedy

The White House says it currently has "no specific agenda" to announce on tackling the problem of gun violence

White House spokesman Jay Carney gave the comments after US President Barack Obama called on Americans to do more to end firearms tragedies.

He said the President still supports a reinstatement of the ban on assault weapons that expired in 2004.

And while Mr Obama would engage Americans "in the coming weeks" on possible approaches, Mr Carney said there're no clear-cut solutions

New York Mayor Michael Bloomberg and dozens of shooting survivors and victims' relatives are also calling on Congress and Mr Obama to tighten gun laws and enforcement.

The mayor appeared at City Hall with 34 people whose own lives or the lives of their relatives have been affected by gun violence around the country.

Mr Bloomberg said something must be done to prevent more loss of lives through gun violence:

"I demand a plan. The time for talk is over. Congress and the White House has to come up with something that stops this carnage no matter what the political ramifications are. Somehow or other we've come to think that getting re-elected is more important than saving lives."

At a vigil for victims of the massacre at Sandy Hook Elementary School in Connecticut, Mr Obama pledged to use all the powers at his disposal to ensure that such tragedies do not recur.

Heart-rending funerals have been held for the 20 children and 6 adults slain last week in the school by gunman Adam Lanza, who also killed himself and his mother
