(CNN) - Walgreens has joined the growing number of retailers asking customers to not openly carry weapons in stores.
Walmart and Kroger announced similar policies this week.
The request follows increasing pressure on businesses to take action to ward off potential massacres at stores and workplaces.
There have been several mass shootings in recent weeks, including one inside a Walmart in El Paso, Texas.
