Groupon has halted gun-related promotions such as deals for shooting ranges and concealed weapons courses in the wake of last month's massacre in Newtown, Conn.

Groupon Inc. spokeswoman Julie Mossler said Tuesday that the move is based on the deals' performance as well as "current customer and merchant feedback." These, she says, have made it "clear they're not a fit right now."

The Chicago company declined to comment further and did not mention the Newtown shootings in its reasoning. There, 20-year-old Adam Lanza killed his mother, 20 children and six educators at an elementary school before shooting himself.

The event has intensified the gun control debate in the U.S. and has led other companies, such as Dick's Sporting Goods, to scale back gun-related business activity, at least temporarily.
