Mexico's newly named ambassador to the United States says he hopes the U.S. imposes new gun-control laws that will help reduce violence in Mexico.

Ambassador Eduardo Medina Mora said Thursday that the mass shooting of school children in Newtown, Connecticut, last month had raised outrage to the point where previously unfeasible legal changes may be possible. Vice President Joe Biden said Thursday that he will deliver new gun-control proposals to President Barack Obama by Tuesday.

Mexico says U.S. guns, particularly assault weapons, help fuel drug cartel-related violence south of the border.

Medina Mora says he hopes the Newtown shooting will, in his words, "catalyze the necessary societal support for a change in the regulations that will be more favorable to the interests of our country."
