U.S. Vice President Joe Biden says he will deliver to the president by Tuesday new policy proposals intended to curb gun violence.

Biden has been holding discussions with gun victims groups and gun safety advocates. He plans to speak later Thursday with a representative of the powerful U.S. gun lobby, the National Rifle Association.

The vice president says a set of recommendations is emerging from his talks likely including background checks for all gun buyers.

His talks come in the wake of the shooting tragedy at Sandy Hook Elementary school in Newtown, Connecticut. Last month, a gunman killed 20 children, six school staff members and his mother before committing suicide.

Meanwhile Thursday, local police in California say two people were shot at a high school. Authorities say police have arrested the shooter, but they gave no other details.
