New York passes tough post-massacre gun law

New York has passed what supporters called the toughest gun ownership law in the country, becoming the first US state to impose new restrictions in the wake of last month's elementary school massacre in Connecticut.

The measures, which include a full ban on sales of military-style rifles, are linked directly to the national horror at the 14th of December massacre of 20 six- and seven-year-olds and six staff at Sandy Hook Elementary School in Newtown, Connecticut. 

Those killings sparked a major national debate over the need for curbing America's liberal gun laws. 

President Barack Obama has also said he would unveil his own proposals later today.
