PARIS (Reuters) - Europol said on Monday authorities from seven countries had arrested 18 people of different nationalities suspected of money laundering and illegal tobacco trade.

Police have dismantled an international organized crime group which was involved in the large-scale illegal trade of tobacco, Europol said.
