Kroger is raising the minimum age to buy guns at its Fred Meyer stores, the third major retailer to place restrictions on gun sales that exceed federal law.
The nation's largest grocery chain said Thursday that recent events show that gun retailers need to take action.
Students returned this week to Marjory Stoneman Douglas High School in Florida for the first time since a troubled teenager killed 17 people there, mostly children.
Fred Meyer sells guns at 44 stores in Oregon, Washington, Idaho and Alaska. Assault-style guns sales were ended everywhere but Alaska several years ago. Special orders for those guns are now unavailable in Alaska.
