US President Barack Obama has called for "concrete proposals" on gun control by the end of January, saying "words need to lead to action".

In remarks at the White House, Mr Obama said Vice-President Joe Biden would lead an exploration of options after a mass school shooting in Connecticut.

There have been calls for gun law reform after 26 children and teachers died at Sandy Hook School in Newtown.
