BEIJING - U.S. President Barack Obama is to roll out a set of gun-control measures on Tuesday amid strong opposition from the Republican Party, a defiant show of executive resolution in his last year at the White House.

The move aims to curb gun violence by regulating gun sales and controlling illicit firearms purchases.

According to Attorney General Loretta Lynch, tighter rules will be enforced, including a mandatory register as a gun trader, a narrower loophole that allows buyers to dodge background checks and a crackdown on purchases through intermediaries.

While Obama stressed that the measures will be "entirely consistent" with the constitutional right to bear arms, Republicans, gun makers and weapons enthusiasts argue that the move is a serious infringement of the Second Amendment.

According to the president, although the steps will not solve every violent crime or prevent every mass shooting, it will potentially save lives and spare families the pain and extraordinary loss as a consequence of firearms being in the wrong hands.

In his weekly radio address on Friday, Obama blasted Congress for failing to act on curbing gun violence.(Xinhua)
