Mayors from Massachusetts and Rhode Island have announced a partnership aimed at reducing illegal gun trafficking and gun violence.

Boston Mayor Marty Walsh joined Providence Mayor Jorge Elorza and law enforcement officials at the New England Regional Gun Violence Summit in Providence.

Walsh announced a new program that brings several cities, including Boston and Providence, together with nonprofit Arms with Ethics to take part in a multi-city pilot program in the New England region.

Arms with Ethics will work with mayors and police leaders in selected cities to develop customized law-enforcement led projects focused on preventing the illegal flow and illegal use of guns. The Boston Foundation will fund the initiative.

Elorza says working regionally will help cities and town crack down on the illegal gun trade.
