A bipartisan legislative task force in Connecticut has agreed on a major overhaul of the state's gun laws in the aftermath of December's deadly attack on an elementary school, lawmakers announced Monday.

The draft legislation would add more than 100 types of guns to the state's list of banned assault weapons; limit the capacity of ammunition magazines to 10 rounds; ban armor-piercing bullets; require background checks for all weapon sales, including at gun shows; establish safety standards for school buildings; allow mental health training for teachers; and expand mental health research in the state.
