Drug smugglers have used mules to bring narcotics from the tiny Balkan state across Greece's northern border in the past but it has usually been one animal. ``This time we had a big group. We really don't know what to do with them,'' he said. A group of collaborators believed to be waiting for the mules at a Greek village about four km (2.5 miles) from the border fled when they saw the police. ``We have made no arrests, other than the mules,'' the officer said.
