French authorities say police have arrested 39 people in a sting on an Albanian and Kosovar heroin trafficking network.

A local government official in eastern France said more than 200 security officers conducted a series of early-morning raids Tuesday near the border with Germany and Switzerland.

The official said the drug ring accounts for hundreds of kilograms of heroin in the French region of Mulhouse and across the borders. Le Figaro newspaper reports the drugs were being sold in unusually large quantities.
